Hi CFD community,

I am new to CFD but took some university level classes. I have an beginner understanding on the numerical methods such as how to discretize a simple scheme, validate with MEA, review stability using von Neumann method, also learned about the RK time stepping. However, applying my own 1D/2D solver for FDM and FEM (DGM) in the classes helped most (Isentropic vortex and lid driven cavity).

I am now in a master degree and I am reading about turbulence, inevitably RANS is mentionned in Wilcox and Pope. Except for derivation found in books I have a fundamental problem with it: How does one write a RANS solver?

From my limited background, I have trouble picturing where/how the time-stepping is involved. Mainly, from google images I see results that are not time dependent so if I am correct we can't see the eddies at a given time.

Does anyone know any good books teaching about implementing RANS? Is going into the OpenFOAM source code a good idea?

Thanks!
