Abstract

Steam direct contact condensation (SDCC) is an inevitable scene in the field of nuclear reactor systems. Computation fluid dynamics (CFD) simulation is carried to predict the process of SDCC (e.g. dynamic change of the steam and water interface, temperature fluctuation, and pressure oscillation). The result can be used as design criterion of some equipment. This paper presents the CFD based numerical simulation on the effect of steam inlet velocity for SDCC. The condensation process is modeled by using Volume of Fluid (VOF) multiphase flow model. And the two resistance model is performed to simulate the interface heat transfer between steam and water. Meanwhile the thermal equilibrium model is used to simulate the condensation process. The turbulence flow model is performed by employing Large Eddy Simulation model.
