Flow and heat transfer analysis in porous wick of CPL evaporator based on field synergy principle

In the present paper, flow and heat transfer processes under different geometrical structures and different heat flux densities in the porous wick of a CPL evaporator have been numerically studied according to field synergy principle. The calculation results indicate that the heat flux density and geometrical structure, such as fin width and wick height, exert great impacts on the heat and mass transfer efficients of the CPL evaporator, which demonstrates that the field synergy principle may be applied to optimize the configuration of the evaporator and consequently to improve the heat transfer efficient of the CPL system.
