Abstract :
The study treats the calculation of the continuous phase of a multiphase flow, i.e., the numerical solution of the equations for a turbulent incompressible flow. An existing SIMPLE based single-grid algorithm is improved applying the multi-grid method. Numerical experiments for two test cases with up to 3,174,00 finite volumes show the features of the new algorithm, the effect of its parallelization and capability to solve real life problems from engineering on PC clusters
