Water Jet Impingement
 
Dear All, I'm trying to simulate water jet impingement on flat surface as it emerges in stagnant air. I split the domain into two: 1- for the jet development in a rectangular nozzle and 2- the ambient air with the impingement surface as its bottom. My problem is although I tried to assign only water to the first domain while air and water were assigned as the second domain fluids, CFX-Pre kept on adding air to the first domain fluids. Solver then did not give any residuals for the ambient air-water momenta. I wonder if anybody has some experience with similar problem and interested to help.
