1Dynamic simulation and experimental validation of a two-phase closed thermosyphon for geothermal application显示文摘The heat transfer perfonmance of a vertical two-phase closed thermosyphon(TPCT)used in a geothermal heat pump was experimentally investigated.The TPCT is a verticalplain steel pipe with inner diameter of 114 mm and bored 368 m deep underground.Carbon dioxide(CO_(2))is used as working fluid.In the TPCT there is no condensation section.CO_(2)is condensed by the evaporator pf the heat pump,flows into the head of the TPCT and nuns down as a falling film along the inner wall of the pipe.For the heat transfer simulation in the TPCT,a quasi-dynamic model in which the mass transfer between the liquid and vapor phases as well as the conduction heat transfer from the surrounding soil towards the pipe is treated dynamically.However the film flow modeling is based on the Nusselt theory of frilm condenssation.The compauison of the experimental data with the numerical simulation is presented and discussed.Johann-Christoph Ebeling Xing Luo Stephan Kabelac Sebastian Luckmann Horst Kruse 2017Propulsion and Power Research2017,6,2:2
2蒸发器在热虹吸系统中的阻力压降与换热性能的数学建模与分析显示文摘本文在中试规模的热虹吸实验装置上对热虹吸自然循环进行了实验研究,并用微元分析法对蒸发器部分建立了数学模型,用来模拟分析蒸发器管内流体的沸腾换热与阻力压降,并与实验数据进行对比验证。高彦明 罗行 Stephan Kabelac 2009化工进展2009,28,S1:0
