TVC is a kind of typical steam ejector which entrains low pressure steam using the high pressure. Many papers have used CFD simulation methods using the ideal gas equation. However the flow accompanied with phase-transition and high-speed fluid flow or condensation is deviated from the ideal gas behavior. To adjust this discrepancy, the modified form of the Redlich-Kwong equation of state is adopted as the real gas model and the realizable k − ε model, shear-stress transport k − ω model are used as the turbulence model to figure out compressible fluid flow.
