Hi every body
I am going to model a flow field in an enclosure by using power law scheme or hybrid scheme.
But in fvScheme I couldn’t find any of these schemes.
As far as I seen in openFoam solvers the most used scheme for divergence discritization are upwind scheme and linear scheme (also TVD, vanleer …). But these two schemes have some defects.
Upwind scheme: this scheme impose artificial dispersion (false diffusion) which Leeds to unrealistic solution.
Linear scheme (central differencing): causes oscillating answer for high Reynolds numbers and unrealistic solution.
Using power law scheme could overcome these infections.
Does anyone know how these schemes could be implemented?
Thanks for consideration
