振荡热管传热性能与工质物性关系分析
Correlation study on physical properties of working fluids and heat transfer performance of pulsating heat pipes
摘要
Abstract
Deionized water,methanol,ethanol and acetone were chosen as working fluids to investigate operation and heat transfer characteristics of pulsating heat pipes (PHP). The experiment was designed to find out critical physical properties for the heat transfer of PHP under different conditions. The results showed that at small heating power,heat transfer depended on the speed of oscillation,and the key factor was kinetic viscosity. As the heating power increased,oscillatory flow accelerated accordingly,and the differences in frequency and amplitude of temperature oscillation gradually decreased,indicating the heat transfer of PHP was affected by kinetic viscosity,liquid specific heat and latent heat. As the heating power increased to a certain point,oscillatory flows of different WFs became faster and,at this stage,WFs of high latent heat and specific heat were preferable for heat transfer. The correlation study on the physical properties of WFs and the heat transfer performance of PHP may help to understand the heat transfer mechanism and operation characteristics of PHP at different situations and provide reference for the establishment of theoretical model.关键词
