NUMERICAL SIMULATION OF TWO PHASE FLOW AND HEAT TRANSFER IN CPLCONDENSER WITH POROUS WICK

摘要

In the present paper, the Volume of Fluid(VOF) method is introduce to model the two phase flow and heat transfer with phase change in CPL condenser with porous element and the effect of different wall temperature and inlet vapor velocity to condensation phase change interface was studied with numerical simulation method. The results present that a fixed condensation physical interface can be formed on the face of porous wick, which can restrain, even eliminate the pressure oscillation. The reason of the effects are also analysed in this paper.
