Hi,
I am working on implementation of Turbulence Model "Spalartr Allamaras"
If any body know the discretization of convection term and best possible scheme to solve the derivative plz tell me

Hi Vilok,

Spalart-Allamaras, model is one-equation turbulence model first used for aerodynaimcs. and i think for discretization of the convection term should be done with second order upwind scheme. if your problem is stady state then TDMA (Tri-diagonal-matrix-algo.) will be usefull and if transient flow then Forward-Time-marching solution will be usefull. and for pressure-velocity coupling you can use PISO algorithms or Transient SIMPLE methods.
