Hello
Thank you. Yes, I agree with you that Eqs. (7.17-7.19) in the latest version are correct. The issue is still with the latest version. In section 7.2.3.2., "Porous media are modeled by the addition of a momentum source term to the standard fluid flow equations." and this source is Eq. (7.2). So, ANSYS Fluent for porous medium uses the standard momentum equation with the addition of Eq. (7.2) to account for the porous medium.
Now, let's focus on Eq. (7.19) which we agreed is the correct one and it is in terms of the physical velocity. If we substitute Eq. (7.16), you will get a momentum equation in terms of the superficial velocity. This equation is NOT the standard momentum equation with the additional source term of Eq. (7.2) as Section 7.2.3.2 stated. The resulted momentum equation takes the form:
My question is, for the superficial velocity, Does ANSYS Fluent uses the standard governing equations with the additional source term in the momentum (Eq.7.2), if this is the case that contradicts with Eqs. (7.17-7.19), OR the momentum equation I mentioned above is what Fluent really uses?
Please check this and thank you very much for your help.
