Combined liquid vapor flow in cylindrical heat pipes with modified internal geometry
Abstract
The first part is devoted to theoretical treatment of the problem of combined liquid vapor flow in a tube with porous wick. The solution is obtained using separation of variables under known evaporation or suction rate and led to analytical results for low Reynolds numbers. Arbitrary values of Reynolds number require using a finite difference technique. The second part handles the optimization of the heat pipe wick for maximum heat flux. The results show agreement between theory and experiment and improvements in the heat pipe performance.
