自湿润流体的流动与传热特性研究进展
Research progress of flow and heat transfer characteristics with self-rewetting fluid
摘要
Abstract
Self-rewetting fluid is the non-azeotropic solutions satisfied to enjoy a particular surface tension behavior—an increase in the surface tension with increasing temperature. In the case of non-azeotropic compositions,preferential evaporation of more volatile component takes place. Preferential evaporation results in a composition gradient along the liquid/vapor interface,and the surface tension gradient due to the composition gradient induces Marangoni flow that is expected to enhance boiling heat transfer. Moreover,due to the particular surface tension behavior,the thermocapillary effect induces a liquid inflow to the bubble–heater contact area,which induce the liquid spontaneously move to the high temperature dry out region. In this paper,the researches on the flow and heat transfer characteristics of the self-rewetting fluids in the recent decades were summarized,mainly including heat transfer mechanism of the single component fluids,multi component fluids and self-rewetting fluids,the preparation of self-rewetting fluid and flow and heat transfer characteristics of self-rewetting fluid. Furthermore,the applications of self-rewetting fluid in wickless structure,different angles of inclination,microgravity conditions and different types of heat pipes were introduced in detail.关键词
