要約
This paper considers pressure gradient and heat transfer in two-phase heat pipes. A new mathematical model is presented for the better design and manufacture of various types of two-phase heat pipe. The steady-state response of the heat pipe to various heat fluxes in the evaporator and condenser sections are discussed. The mathematical modeling of the fluid flow and heat transfer in the vapor space and liquid film region are described. The momentum equations of both phases coupled and highly non-linear are derived and solved by perturbation method to calculate the film thickness and velocity profiles of the vapor and liquid phases.
