Multiphase

This analysis type is used to simulate the time-dependent behavior of fluid mixtures, for example air and water. The analysis is carried out using the VoF (Volume of Fluid) method which is a standard approach for the computation of multiphase systems. | Page 28

Tutorial project for setting up a Multi-phase flow simulation.

More number of fluids interaction is multiphse flow . courant number greatly influence the stability, convergence , time step . High courant number speeds up the simulation convergence but can lead to instability . Lower courant number enhances stabiity . by selecting the correct courant number we decrease the computational time and we get stability.  

courant number directly proportional to local velocity in centre of the cell and time step . Inversely proportional to length of cell in fluid direction.
