Multiphase flow and courant number

About this project

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.
