Research on Flow and Condensation of Vapor With Non-Condensable Gas in an Inclined Tube

A set of separate heat pipe (SHP) with water as medium has been built in this paper. The flow and condensation of vapor with non-condensable and high partial pressure air in the SHP are measured in the experiment. A series studies are made of the effect on the parameters-coolant water flux, vapor flux, the coolant inlet temperature and the inlet vapor temperature and a lot of reliable data are obtained to analyze the heat transfer process.The physical model of the flow and condensation of vapor-air mixture has been studied and the related numeral model is founded by using the two-fluid model in the Mathematical model. The numerical result agrees well with the experimental data.
