Effect of particle loading on heat transfer enhancement in a gas-solid suspension cross flow

Heat transfer between gas-solid multiphase flow and tubes occurs in many industry processes, such as circulating fluidized bed process, pneumatic conveying process, chemical process, drying process, etc. This paper focuses on the influence of the presence of particles on the heat transfer between a tube and gas-solid suspension. The presence of particles causes positive enhancement of heat transfer in the case of high solid loading ratio, but heat transfer reduction has been found for in the case of very low solid loading ratio (M _s of less than 0.05 kg/kg). A useful correlation incorporating solid loading ratio, particle size and flow Reynolds number was derived from experimental data. In addition, thek-∈ two-equation model and the Fluctuation-Spectrum-Random-Trajectory Model (FSRT Model) are used to simulate the flow field and heat transfer of the gasphase and the solid-phase, respectively. Through coupling of the two phases the model can predict the local and total heat transfer characteristics of tube in gas-solid cross flow. For the total heat transfer enhancement due to particles loading the model predictions agreed well with experimental data.

Three dimensional free convection couette flow with transpiration cooling

INTRODUCTION In recent years, the subject of free convection flow has attracted the attention of a number of scholars because of its possible applications to several geophysical problems. In view of these applications, a series of investigations were made to study the flow past a vertical wall. Transpiration cooling can very effectively pro-tect certain structural elements in turbojet and rocket engines, like combustion chamber walls, exhaust nozzles or gas turbine blades from hot gases. …     

Arrangement strategy of ground heat exchanger with groundwater

The orientation strategy of side pipe and the heat transfer performance of six ground heat exchangers(GHEs) were optimized by numerical simulation,with soil being treated as a porous medium.An experiment on the heat transfer of four GHEs was carried out in 2010.Results indicate that the velocity field is disturbed by GHEs.The optimal orientation strategy of side pipe is that the upward pipe is located upstream and the downward pipe downstream.The space between GHEs should be appropriately adjusted,depending on the direction and flow velocity.Groups of GHEs should be installed perpendicular to the mainstream in a single row,but if the acreage does not meet the requirements,GHEs should be installed in staggered multiple rows.Fewer GHEs parallel to the mainstream strengthen the heat transfer.Moreover,numerical results agree well with the test data,with the maximum relative error being less than 7.7%.     

An exact analytical solution for convective heat transfer in rectangular ducts

An exact analytical solution is obtained for convective heat transfer in straight ducts with rectangular cross-sections for the first time. This solution is valid for both H1 and H2 boundary conditions, which are related to fully developed convective heat transfer under constant heat flux at the duct walls. The separation of variables method and various other mathematical techniques are used to find the closed form of the temperature distribution. The local and mean Nusselt numbers are also obtained as functions of the aspect ratio. A new physical constraint is presented to solve the Neumann problem in non-dimensional analysis for the H2 boundary conditions. This is one of the major innovations of the current study. The analytical results indicate a singularity occurs at a critical aspect ratio of 2.4912 when calculating the local and mean Nusselt numbers.     

Experiments and sensitivity analyses for heat transfer in a meter-scale regularly fractured granite model with water flow

Experiments of saturated water flow and heat transfer were conducted for a meter-scale model of regularly fractured granite. The fractured rock model (height 1502.5 mm, width 904 mm, and thickness 300 mm), embedded with two vertical and two horizontal fractures of pre-set apertures, was constructed using 18 pieces of intact granite. The granite was taken from a site currently being investigated for a high-level nuclear waste repository in China. The experiments involved different heat source temperatures and vertical water fluxes in the embedded fractures either open or filled with sand. A finite difference scheme and computer code for calculation of water flow and heat transfer in regularly fractured rocks was developed, verified against both the experimental data and calculations from the TOUGH2 code, and employed for parametric sensitivity analyses. The experiments revealed that, among other things, the temperature distribution was influenced by water flow in the fractures, especially the water flow in the vertical fracture adjacent to the heat source, and that the heat conduction between the neighboring rock blocks in the model with sand-filled fractures was enhanced by the sand, with larger range of influence of the heat source and longer time for approaching asymptotic steady-state than those of the model with open fractures. The temperatures from the experiments were in general slightly smaller than those from the numerical calculations, probably due to the fact that a certain amount of outward heat transfer at the model perimeter was unavoidable in the experiments. The parametric sensitivity analyses indicated that the temperature distribution was highly sensitive to water flow in the fractures, and the water temperature in the vertical fracture adjacent to the heat source was rather insensitive to water flow in other fractures.

Analysis of Combined Natural Convection and Radiation Heat Transfer in a Partitioned Rectangular Enclosure with Semitransparent Walls

In this paper, we present a two-dimensional numerical analysis of the conjugate natural convection and radiation heat transfer in a double-space enclosure with two semitransparent walls. Two kinds of boundary conditions are considered, the first being the isothermal process of the opaque wall, and the other the incidence of a constant radiation flux in the left semitransparent wall. The renormalization group k – ε model is adopted to simulate the turbulent flow in the enclosure. To compute the radiation heat transfer in a semitransparent medium, the discrete ordinates model is used. We compare the behaviors of enclosures with single and double semitransparent walls and determine the difference in the results obtained for semitransparent and opaque partitions. The results indicate that a semitransparent partition facilitates a reduction in the heat loss or obtains a higher temperature distribution. The transmittance of a semitransparent wall has a great effect on the thermal and flow characteristics in an enclosure. The change of wall temperature is found to be significant when the thermal conductivity values range from 0.05 to 0.5 W/(m·K), and to be small when ranging from 0.5 to 10 W/(m·K). These conclusions are helpful for green design and energy saving in solar buildings.

Numerical Study on Heat Transfer and Flow Characteristics for Laminar Flow in a Circular Tube with Swirl Generators

This study investigated the heat transfer and flow characteristics of one kind of swirlgenerator in a circular heat exchanger tube through a numericalsimulation. The swirlflow induced by this type of swirlgenerator can obtain a high heat transfer rate with minimalpressure drop penalty. The simulations were carried out to understand the physicalbehavior of this kind of mesoscale heat enhancement component. By visualizing the heat transfer and flow characteristics, it is found that the swirlflow is induced by swirlgenerator in the circular tube couples with the impinging jet effect. After passing through the swirlgenerator, the localfriction factor of liquid can quickly return to lower levelmore quickly, while the localNusselt number maintains higher values for a distance; thus, the evaluation criterion of localperformance is improved. Single-factor optimization is used for three geometric parameters, i.e., the angle of swirlgenerator(25o, 45o, and 60o), the length of swirlgenerator(0.005, 0.01, and 0.02 m), and the center rod radius(1, 2, and 3 mm). The optimum parameters of the swirlgenerator for laminar flow of air in a circular tube are obtained, which should be 60o, 0.005 m, and 3 mm, respectively.     

Effect of Flow Directions on Multiphase Flow Boiling Heat Transfer Enhanced by Suspending Particles in a Circulating Evaporation System

A circulating fluidized bed evaporator(including down-flow, horizontal, and up-flow beds) was constructed to study the effect of flow directions on multiphase flow boiling heat transfer. A range of experimental investigations were carried out by varying amount of added particles(0-2%), circulation flow rate(2.15-5.16 m~3/h) and heat flux(8-16 kW/m~2). The comparison of heat transfer performance in different vertical heights of the horizontal bed was also discussed. Results reveal that the glass bead particle can enhance heat transfer compared with vapor-liquid two-phase flow for all beds. At a low heat flux(q = 8 kW/m), the heat-transfer-enhancing factor of the horizontal bed is obviously greater than those of the up-flow and down-flow beds. With the increase in the amount of added particles, the heat-transfer-enhancing factors of the up-flow and down-flow beds increase, whereas that of the horizontal bed initially increases and then decreases. However, at a high heat flux(q=16 kW/m), the heat-transfer-enhancing factors of the three beds show an increasing tendency with the increase in the amount of added particles and become closer than those at a low heat flux. For all beds, the heat-transfer-enhancing factor generally increases with the circulation flow rate but decreases with the increase in heat flux.

Nothing in the History of Spanish <Emphasis Type="Italic">Anís</Emphasis> Makes Sense,Except in the Light of Evolution

We describe, discuss and illustrate a metaphoric parallel between the history of the most famous Spanish liqueur, “Anís del Mono” (Anís of the Monkey), and the evolution of living organisms in the light of Darwinian theory and other biological hypotheses published subsequent to Charles Darwin’s Origin of Species. Also, we report the use of a caricature of a simian Darwin with a positive connotation, perhaps the only one ever produced. We conclude that, like some species in the natural world, Anís of the Monkey has evolved, adapted, survived and become the fittest and most successful anís in the Spanish market and possibly the world. We hope this paper will contribute a new useful metaphor for the teaching of biological evolution.

Global technologies,local practices

ABSTRACT

This special issue of Learning, Media and Technology contributes to a growing need, not only for critical accounts of digital education that resist the global, but also for a more diverse representation of the multiplicitous practices of teaching and learning with technology across the globe. It builds on important work that has examined open education initiatives in the Global South [Arinto, P. B., C. Hodgkinson-Williams, and H. Trotter. 2017. "OER and OEP in the Global South: Implications and Recommendations for Social Inclusion." Adoption and Impact of OER in the Global South, 577–592] and highlighted ‘missing voices’ in educational technology development [Davis, R. 2015. The Missing Voices in EdTech: Bringing Diversity into EdTech. Thousand Oaks, CA: Corwin Press]. It is through such critical enquiry that research can continue to cut through the discursive regimes of simplistic disruption and enhancement from a pervasive education technology industry. This means aligning research in this area, less with grand narratives that portray digital education as an external and universal force capable of radical transformation, and more with accounts that acknowledge an already-present political economy of educational technology, in which specific devices and applications succumb to everyday practices of negotiation, consumption, and resistance, particular to the contexts in which they manifest.

Gjesme, Torgrim (1971). Motive to Achieve Success and Motive to Avoid Failure in Relation to School Performance for Pupils of Different Ability Levels. Scand. J. educ. Res. 00, 81‐99. Subjective probability of success (P_s) has been a neglected factor in studies regarding the relationships between achievement‐related motives and performance. Taking this factor into account, we expected that in a traditional classroom in which ability is heterogeneous, only pupils of average ability would have their achievement‐related motives aroused. The very bright pupil would not have his motives aroused, while the dull one would have his motive to avoid failure (Mf) aroused, but not his motive to achieve success (M,). The pattern of our results was in consonance with the hypotheses for boys in 7th grade.

     

SOME PERCEIVED IMPEDIMENTS TO TECHNOLOGY TRANSFER FROM THE HIGHER EDUCATION SECTOR OF THE EUROPEAN COMMUNITY TO INDUSTRY

The effective exploitation of the applicable resources in the Higher Education (H.E.) Sector of the European Community has been accepted as a major factor for future economic prosperity. Member States have, however, to‐date, not obtained the optimal benefit from these resources, as, inter alia, their commercialization and marketing have not been effectively implemented. It has also been recognized that strong and efficient transnational linkages, bringing together research expertise throughout the Community, are essential if the challenges from Japan and the United States are to be met on world markets. The identification and removal of the impediments inhibiting beneficial academic technology transfer are therefore fundamental pre‐requisites for successful utilization and exploitation. Some of the perceived impediments can be categorized as: Basic ‐‐ impediments common to Member States, including the mental/attitudinal gap between the H.E. and the Industrial Sectors; Institutional ‐‐ basic impediments in academic institutions, in particular, the absence of factors needed to generate the required environment for beneficial technology transfer; Industrial ‐‐ impediments, such as the inability to identify the actual needs of Industry; Governmental ‐‐ impediments arising from a lack of assessment of governmental policies, i.e. the ownership of publicly funded research results. The removal of impediments will require empirical studies on their causes, a task which will entail the services of staff trained and experienced in all aspects of academic technology transfer. It will also necessitate cultural and organizational changes both in the H.E. and the Industrial Sectors.
