Simulation of Complete Liquid-Vapor Phase Change inside Divergent Porous Evaporator

Omar Rafae Alomar, Miguel A. A. Mendes, Dimosthenis Trimis, and Subhashis Ray
Abstract—Complete phase change process within a divergent porous evaporator is numerically investigated in this paper. A smoothing algorithm, proposed by the present authors, is used in order to deal with the discontinuity in effective diffusion coefficient. Effects of various parameters on the temperature distribution are carefully investigated, which clearly indicate that operating conditions and the geometry of diffuser strongly influence the outlet condition of steam, whereas, porous media properties have only minor impact.

Index Terms—Complete phase change, divergent evaporator, porous media, smoothing of diffusion coefficient.
