Turbulance Model
 
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

Re:Turbulance Model
 
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.
