CFD simulation of steam condensation in a subcooled water pool

In present work interfacial dynamics of steam injection to a sub cooled stagnant water pool using a vertical blowdown pipe has been simulated using ANSYS FLUENT 14. Multiphase Volume of Fluid (VOF) model is used to track the interface and standard k-є model was adopted for modeling the turbulence. Effects of pool temperature and steam injection velocity are explored to understand the hydrodynamic and thermal characteristics of the pool. Also the effect of both these parameters on the rate of condensation is investigated. It has been observed that increase in the steam injection velocity will decreases the interfacial temperature which in turn enhances the rate of condensation.
