pressure correction methods

clifford bradford

Hello gentlemen, i'd like to start a discussion on pressure based methods (SIMPLE, PISO etc) i am familiar with time based approaches (unsteady formulation) as that's what i've learned in my classes. however pressure based approaches seem very popular especially for steady incompressible flow. i'd like if we can provide descriptions of these methods, references, implementation of boundary conditions, application to compressible and unsteady flows, comparision to time based approaches and anything else you might think appropriate. I'd like to do this for the benefit of the forum as well as for my own personal edification. even though these schemes are considered "old" i think they are implemented in many commercial packages so i think i'd be good to discuss them.
