ssj New Member sscfd Join Date: Jun 2013 Posts: 20 Rep Power: 12	I am working on 3d simulation of flow in a vortex tube by the ANSYS CFX14.5. I have problem with validating experimental data to cfd results. my B.C is: Inlet nozzle: Total pressure(7.2bar) with static temp: 290k Cold Outlet: static pressure:0 bar gauge Hot Outlet: with varying static pressure so as to vary the cold fraction at the hot end to obtain optium value. could you please help me what should i do? as i expect according to my exp data, my cfd cold temperature shouldn't began minimum whith regard to cold fraction.(as i seen in related[IMG]desktop[/IMG] published articles about VT) is it clear my question? with regards
