Abstract

CFD analysis has been carried out in this paper. The purpose is to reveal the understanding of flow phenomena inside the ejector on the performance of steam ejector using three well known turbulence models. In this study, the ejector design was modeled using finite area CFD techniques to resolve the flow dynamics in the ejectors. Furthermore, from this study it can be concluded that by employed vary of turbulence models there are different results in pressure distribution, in contour of Mach number and in Entrainment ratio inside the steam ejector.
