Flow and heat transfer characteristics in the porous wick condenser of CPL

摘要

An analytical investigation has been conducted to understand the internal fluid flow and heat transfer in the condenser with porous wick of an innovative apillary pumping loop (CPL) system. A mathematical model is proposed and used to describe the flow and heat transfer, especially interfa- Cial transport phenomena. The liquid-vapor interface of the condensed liquid film was numerically deter- Mined. Some factors, such as vapor pressure, wall subcooling, wall heat load and thermofluid proper- Ties, have significant influence on the heat transfer process and the shape of liquid-vapor interface.
