Progress of research on visualization of internal procedure of two-phase closed thermosyphon and its heat transfer enhancement
摘要
Abstract
Two-phase closed thermosyphon(TPCT) contains two phase flow and phase change process. The traditional theory analysis and experimental study cannot intuitively give concretize process including two phase flow,heat and mass transfer and evaporation-condensation phase transformation. This paper introduced common TPCT heat transfer model,generalized theoretical research on heat transfer and fluid flow in condensation section,insulation section and evaporation section,and summarized the actuality of visual research on its internal procedure by experimental and numerical computation method. Computational fluid dynamics(CFD)makes it possible to do numerical visualization research on TPCT with actual interior situation of TPCT guaranteed. Besides,the paper presented domestic and foreign CFD research findings and simulation level and pointed out the domestic research on TPCT using CFD method lagged behind relatively. Meanwhile,the heat transfer enhancement method of TPCT was summarized systematically,especially the efficient fluid medium with the fouling problem solved in the course of heat transfer enhancement. The research status and focus on the heat transfer enhancement of nanofluid and self-wetting fluid were introduced emphatically. Lastly,CFD method was suggested to do numerical visualization analysis on concrete details of TPCT internal flow course,evaporation and condensation,and heat and mass transfer. The combining of experimental result,theoretical calculation and numerical research pioneered a new way to go deep into TPCT interior mechanism.关键词
