Two-Fluid Finite Volume Solver for Wet Steam Flow
Abstract
This work focuses on the numerical simulation of wet steam flow using a two-fluid model, which is augmented with condensation model equations. The commonly employed explicit schemes had to be adapted to account for real-gas and real-liquid equation of state. Since the model includes a highly stiff drag term, the implicit LU-SGS scheme is employed to reduce computational time. The proposed approach is validated using a two-dimensional Barschdorff nozzle test case.
