Differencing scheme for k-eps model

Ron Barer

Hello,

to calculate the convective fluxes of the momentum equations within the finite volume method one can often choose between upwind (1st order) or central (2nd order) or have a mix. So if I understood it right higher order means faster convergence to grid independent solution. (Right ?) Now my question. Has the choice of the differencing scheme the same influence concerning the k and eps equations ? Are there some numerical reasons why the differencing scheme in the turbulence equations is less important than in the momentum equations ?

Cheers,

Ron
