Negative Absolut Pressure In Cavitating Flow -- CFD Online Discussion Forums

Roozbeh Guest Posts: n/a	Hi all; I want to work with cavitation option of Fluent. In help of fluent6.0 there is an example: velosity inlet=10m/s , Pv=101175pa For this case I have no problem and my results is the same as fluent help results. But for the same cavitation number and inlet velosity=40m/s , Pv=2400pa(at ambient temprature) ,I have a negative absolute pressure i.e. a very low gage pressure. I am now trying to get a better resuls by low underrelaxation factors at O(.001). Note that both liquid and vapor assumed incompressible. What's your opinion?
