Abstract

In order to comprehend fluid dynamics of gas-liquid two phase flow through plate heat exchangers flow of HFE7000 between inclined parallel plates has been numerically inverstigated based on a mixture model for gas-liquid two phase flow with the phase changes. The characteristics of the flow patterns for various flow configurations were discussed and both the Nusselt numbers and pressure drops were evaluated. As the results using plate heat exchangers, that the gas-liquid phase change could effectively enhance the heat transfer between the working fluid and the surfaces, and the prefered orientation for the installation of the plates could be identified based on the combination of the heat transfer coefficient and the pressure drop.
