ke model
I am working on NS codes using BaldwinLomax turbulence model for last five years. I would like to try my codes with kepsilon models. Can any CFD member help me by giving more details of ke model, preferably FORTRAN source code. Otherwise, I have to write the code, debug and validate, which take time, which I feel unnecessary.

Re: ke model
First of all, you can find these two equations in any CFD related journal papers. Whether it is 2D form, 3D form, Cartesian coordinates, cylindrical coordinates, incompressible, compressible form. That is the starting point. Then you need to know what NavierStokes equations you are trying to solve. Whether it is steady state, or unsteady state, compressible of incompressible. Then you need to decide what numerical method you are going to use. This will determine how the twoequation model will be solved. As you see, the method of solving the twoequation model depends on the problem formulation. The programming is straightforward, but the source terms in the twoequation model can create some convergence problem for you ,if you are not carful.

Why don't u look at this software called PHOENICS by CHAM Pte. Lmtd. They use a ke model for their soultion. I'm currently using their PHOENICS1.5EO in my final year project. I'm currently pursuing an aeronautical degree from University Technology of Malaysia

Re: ke model
There is a TEACH program,with source code available,using staggered grid approach. This maye a good approach to learn what other people are doing. In general, this is a high Reynolds number model with special wall function treatment. The algebraic model normally solve the flow field all the way to the wall. You also need to worry about the single grid vs staggered grid issue,
