yaseen wsu is on a distinguished road
hello
I simulated free surface flow but the result show a very large difference between CFX and experiment, as well I take measurements at VF 0.1 at the location shown in attached image (has high air concentration) so:
1- CFX can predict flow in such condition?
2- I used supercritical outlet boundary condition according to ANSYS CFX guide and homogeneous multiphase flow
please help me in this problem.
