i mean how to calculate pressure,viscous and porous forces ?
and lift and drag coefficient on the body
Maybe this is what you are looking for: https://www.youtube.com/watch?v=J944HOj_4b0
the problem in using that method is that the viscous force is neglected which affect the result for drag coefficient considerably
I want to ask about the porosity value how it is included in simscale ?
It is not clear for me how to include values for porosity in simulation for porous media
or the flow resistance is included as source terms without any changes in the momentum equation ???as some terms in the momentum equation for flow in porous media include porosity
can anyone help ?
