I was wondering what's the actual and preferred expression for the compressive term in gamma equation and a very brief explanation of how it is derived. The formula for 'phir' in the code differs from what Henrik has mentioned in (Eq. (4.15)). In the code:
phir=cGamma()*mag(phi/mesh.magSf())*interface.nHatf() while Henrik's suggests (if I have formulated it correctly): phir=cGamma*nhatf*max(nhat * phi / mesh.magSf()**2 ) Are they really different (am I missing something) and if yes, which one is better? 2) where is the smoothing function for 'gamma' in interFoam? Does it have a significant effect on VOF performance or just affects surface tension prediction? thanks |
