 February 14, 2011, 02:23 Free Surface Flow #1 New Member   Vishal Join Date: Feb 2011 Location: Bhopal, M.P. (India) Posts: 18 Rep Power: 7 Hi Dear all, I want to use ANSYS CFX to model a jet of water coming out of nozzle impinging on a flat plate. The inlet boundary condition is Velocity at the inlet of the nozzle. What can be the outlet boundary conditions and the expressions for creating the jet of water in air? Please help me.

Your outlet can probably be an outlet or opening. Which is best will depend on exactly what you are modelling.

Also regarding the boundary conditions you can choose a pressure outlet as the boundary by taking a sufficiently large CV.

Outlet boundary condition will be opening to atmosphere i.e., constant pressure at outlet. But I've not got the results accurately. Some expressions or functions needs to be defined. Please Can you suggest me what expressions should I create?

Please someone help me in creating the expressions. I've tried many but the results using function calculator and theoretical results vary by about 9.72% which is vary large.
