A fully developed square channel flow with a Reynolds number of Re = 4410 (based on bulk velocity and duct width) has been calculated using Large Eddy Simulation (LES) technique with the Smagorin-sky eddy viscosity model. Results for the Prandtl's secondary motion which is turbulence-driven show good qualitative picture and are in good quantitative(More)
The present 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 3 174 400 finite volumes show the features of(More)
