'Best' algorithm for CFD on unstructured 2d grids?

andy2o

Dear All,

I have used CFX and other commercial codes, and have a good background in scientific programming. Now, mainly for my own interest and education, I wish to develop my own (toy) code for 2-d CFD on an unstructured grid. I hope to implement k-epsilon and maybe k-omega models within this code....

So my question is:

1) Do you know of a good, robust algorithm for simulating turbulent flow on an unstructured 2-d grid?

2) Can you point me towards a good reference which describes it?! One that gives enough detail to replicate the method if possible?

I would prefer to work with an algorithm using collocated variables (pressure and velocity at same nodes) but I am open minded and can be convinced otherwise by good evidence.

All references would be very welcome - but I would particularly welcome information about algorithms that are well-proven and general purpose, even if they are not state-of-the-art.

Very many thanks for your help.

Best regards, andy2o
