Gravity in 2D axisymetrical situations
 

Hello

I am wondering how gravity can be taken into account in 2D axisymetrical situations (like tube) by classical formulations used in the common CFD packages Is it really possible ?

Thanks for your help

Yes, if the gravity is directed along the axis of symmetry. If not, with the gravity the problem is not axisymmetric and needs 3D solution.

Thanks a lot I understand clearly
