Dear all,
I am working with Fluent and I have simulated a flat plate and the mesh is enogh fine (Y+<=1). The turbulence model that I use is k-w SST and I uncheck Low-Reynolds-Number in the turbulence panel. I export the omega value on the plate surface and now I am trying to find what equation fluent uses for it. It would be appriciated if you help me about the equation. I used this equation but the answer was not the same with Fluent. OMG=sqrt(OMG_vis^2+OMG_log^2) OMG_vis=6*ro*(U_tau^2)/(0.075*Mu*Yplus^2) OMG_log=ro*(U_tau^2)/(0.3*k*Mu*Yplus) ro=dinsity U_tau=friction velosity Mu=viscosity k=0.41 |
