Numerical solution of transonic flow of steam with non-equilibrium phase change using typical and simplified method
Original language description
Simulation of transonic flow of steam with phase changes represents rather complex problem. One has to consider several simplifications to obtain a flow model, which is computationally adequate. Typical current simulations are based on the solution of transport equations for the mixture and additional transport equations for the liquid phase. The creation of new droplets and the growth of already existing droplets is included in the form of source terms, which require a special treatment for time integration. The aim of this paper is to compare an alternative simplified method with a typical method. The alternative simplified method uses no additional transport equations and the non-equilibrium phase change is included in a form of switch from the meta-stable state to the equilibrium state, i.e. switch from the zero to the equilibrium wetness. Although this simplified method cannot provide details about droplet size, it can still be interesting tool for the early steps of the turbine design. Both methods are based on the numerical solution of governing equations using a finite volume method. The advantages and disadvantages of simplified method with respect to typical method are discussed and demonstrated on simulations of flow in nozzle and turbine cascades.
