Simulating the dynamics of fluid-cylinder interactions

We present the simulation of the dynamics of fluid-cylinder interactions in a narrow three-dimensional channel filled with a Newtonian fluid, using a Lagrange multiplier based fictitious domain methodology combined with a finite element method and an operator splitting technique. As expected, a settling truncated cylinder turns its broadside perpendicular to the main stream direction and the center of mass moves to the central axis of the channel. In the case of two truncated cylinders, they first move around each other for a while and then stay together in a "T" shape. After the "T" shape has been formed for a long enough time, we found no vortex shedding behind the cylinders. When simulating the fluidization of 60 truncated cylinders, we captured the features of interactions among fluidized cylinders as observed in experiments.     

农民工与和谐社会建设

农民工向城市的流动是经济社会发展的必然结果。然而,农民工在城市从业、社会保障、子女入学等方面并没有享受到应有的保障,因而造成了农民工阶层流动的障碍,使产业结构与社会结构不协调,很不利于和谐社会建设。为解决这一问题,需要清除一切阻碍农民工向城市流动的障碍;调节收入差距,健全社会保障制度,制定并完善保护城市农民工的法规;提倡农民"离土不离乡"。     

振荡电偶极子在各向异性媒质中的总辐射功率

对各向异性媒质中电磁场辐射问题的研究．已完成了电偶极子的辐射电磁场及能流密度表达式的推导，章进而在各向异性球坐标系中通过球面积分先求得在各向异性媒质中电偶极辐射的总功率，再通过坐标变换回到各向同性坐标系中．得到用通常直角坐标系表述的电偶极在各向异性媒质中辐射总功率的表达式．当媒质为各向同性时其结果与预期的结果相吻合，验证了推导结果的正确性．利用该结果可对电偶极在各向异性媒质中的辐射效果做出判断，而且为测定各向异性媒质中电偶极辐射的总辐射功率提供了理论依据，从而谋求开发与应用．     

Effect of Ultrafine particles on Flow Field and Transport Properties near the nterface Around a Moving Bubble

Laser Doppler Anemometer has been used to measure the flow field characteristics near the interface around a moving bubble in the presence of ultrafine particles. In order to model a moving bubble, the bubble was fixed into the counter-flow liquid by a metal mesh. Experimental materials are air and water, and the particles are complex oxidate powder. Experiments were carried out under the operating conditions: the liquid flow velocity u0 is 12.6 cm/s, the equivalent diameter de is 0.6 cm, the mass concentration of particle is 0.2%,the average particle diameter is about 10 nm and the density is 2 g/cm3. The velocity profiles of both frontal and tail-vortex areas were measured respectively. The experimental results show that the velocity fields are obviously changed in the existence of particles. In the frontal area of the bubble, both tangential and normal velocities decrease due to the presence of particles, but in tail vortex area, the tangential velocities increase remarkably, and normal velocities rise gradually from the center towards the fringe in the opposite tendency to that of no particles. The influences of flow field change in the presence of particles on gas-liquid mass transfer are analyzed and discussed.
