The pressure correction method (Q1073661)

The pressure correction technique for solving the Navier-Stokes and Euler equations is studied. A general pressure correction analysis is presented using the full form of the linearized momentum equations. it is shown how the simple procedure results from adopting the most approximate form of the momentum equations. Two extended pressure correction techniques are derived using higher-order approximations and shown to be up to 50 \% faster than SIMPLE on a test example. Finally, a number of alternative approaches are considered and their performance evaluated against SIMPLE.
