Heat transfer characteristics of air cross-flow for in-line arrangement of spirally corrugated tube and smooth tube bundles

An experimental study on heat transfer and resistance coefficients of linearly arranged smooth and spirally corrugated tube bundles in cross-flow was performed. The heat transfer and resistance coefficients are presented in this paper with transverse and longitudinal tube-pitch and tube geometries taken into account. The experiment's results can provide technical guidelines for application to horizontal air preheater with arranged in-line spirally corrugated tube bundles, especially to the air preheater for CFBCBs (Circulating Fluidized Bed Combustion Boilers).     

《东南日报》与“八·一四”空战

1937年8月14日,中日空军在杭州地区上空发生一次大规模的空战。对这次空战,《东南日报》作了声势浩大的报道,报道内容也十分翔实,不少还是独家新闻。"八·一四"空战揭开了抗战和"二战"空战的序幕。《东南日报》对这次空战的报道,也在新闻史上留下了不朽的一笔。     

抓好队伍·营造环境·协调关系——《空军工程大学学报(自然科学版)》办刊体会

从刊物特色、队伍建设、营造环境、协调关系等方面介绍了《空军工程大学学报(自然科学版)》的办刊体会.认为:抓好编辑队伍、稿源队伍、特约编委队伍建设是办好期刊的"基础条件",培养"服务,团结,进取,创新"的理念是办好期刊的"内部要素",协调好内外关系是办好期刊的"外部条件".     

空勤人员的都市休闲

空勤人员因工作紧张程度高、窗内环境密闭、光照规律多变、远离自然、静坐有余而活动不足等成为了这类症状的高危人群。同时又没有1种"诗情画意"的休闲方式能使空勤人员这类特殊人群通过亲近自然的休闲活动的调整,使工作中积累的压力得到缓解,达到身心健康、精神放松,效率提高。本篇介绍几种适合空勤人员的特殊消费群的休闲方式供大家参考。     

少林禅武思想对空中极限运动内在价值的诠释

以少林禅武思想作为“他者的视角”对空中极限运动的内在价值进行诠释,将西方哲学视域下的“自我肯/否定”补充和升华至无念无住的无我之境,为生活在“常人”世界的当代人通向本真之路另辟一条蹊径.     

The impact of electric overhead radiant heating on the indoor environment of historic churches

The impact of electric overhead radiant heaters on the microclimate, air flows, transport and deposition of suspended particulate matter (SPM) was monitored between March 2004 and March 2005 in the historic churches of Saint Michael Archangel in Szalowa and Saint Catherine in Cracow (Poland). The measurements show that although irradiation at the floor level increases temperature and reduces relative humidity in the interior of the church, the effect out of the heated zone and for the surfaces sheltered from irradiation is very limited, i.e. their extent is comparable with natural fluctuations inherent to the local climate of the church. The radiant heaters proved to generate little convectional flow of the air. Therefore, the heating system was not found to increase the concentration of SPM indoors; in particular, no re-suspension of particles already present in the church was observed. This work has demonstrated that the overhead radiant heaters are capable of providing localised heat to the areas where people congregate without adversely affecting painted walls and the works of arts displayed in churches. Care, however, should be taken that sensitive works of art are not exposed to the direct infrared radiation.
