Abstract

In the present paper a semi-implicit predictor corrector method is developed, for the solution of the two-dimensional compressible Navier-Stokes equations in the presence of two phase flows. In evaluating the predicted and corrected solution, the pressure effects are accounted for implicitly by satisfying simultaneously the conservation of mass and momentum with the constraint of the equation of state. To avoid the use of a direct method for solving the equations, a Jacobi-type iterative procedure is used. The efficiency and accuracy of the method have been demonstrated by using the proposed approach for solving several complex flow configurations like: single phase flows in internal combustion engines; non evaporating liquid sprays in ambient. The computed results show good agreement with experimental and/or numerical data available in the literature.
