超临界CO2的管内对流换热研究

概述了超临界CO2流体管内对流换热的研究,指出了影响换热的主要因素有热流密度、浮升力、压力、润滑油等,提供了多种公开发表的超临界流体在冷却工况下的换热关联式,同时指出了现有研究内容的不足。

Research on Convection Heat-Transfer of Supercritical Carbon Dioxide Flow In-tube

This paper gives a review of the heat transfer of supercritical carbon dioxide in-tube flow and points out that the main factors to influence heat transfer are heat flux, buoyancy, pressure,lubricant and so on.Some published correlations for heat transfer coefficient during in-tube cooling are collected. The shortages of current researches are pointed out.
