Abstract :
This paper describes a CFD based strategy for the modelling of two-phase flows condensation in LHP system’s with heat and mass transfer using ANSYS FLUENT 13. Multiphase Volume of Fluid (VOF) model is used to track the interface and standard k-є model was adopted for modelling the turbulence. Effects of wall temperature and vapour injection velocity are explored to understand the hydrodynamic and thermal characteristics of the capillary condensation process. In addition, the effect of both these parameters on the rate of condensation is investigated. The technique is based on a recently derived phase field model for boiling and condensation phenomena. The results showed that the phase field model fit best the literature’s results.
