CFD is expected to have a major role to play in optimizing the design of steam injector. However, it is very difficult to simulate hydraulic phenomena in the stream injector because it contains various kinds of problems such as complicated geometries, multiphase flow, free surface, phase change and turbulence. Therefore, for the purpose of numerically simulating thermal hydraulic phenomena in steam injector system, we adopt the advanced CFD techniques such as CIVA and T-CUP methods. In this paper, the analysis algorithm is briefly described. Then we simulate three-dimensional thermal hydraulic phenomena in some case of steam injectors with adopting temperature recover method as a phase change model. And we check adequacy of our code for simulatie Steam injectors.
