Please find attached PDF to know more about my problem.
I am giving folloing boundary conditions -

inlet (Pressure Inlet)
Momentum
• Reference frame : Absolute
• Gauge total pressure : 600000 Pa
• Supersonic/Initial gauge pressure : 0 Pa
• Tubulence Specification :Intensity – 5%
: Hydraulic dia – 9.8mm
Thermal
• Total temp : 300 K


h_out (Pressure outlet)
• Gauge pressure : 0 Pa (open to environment)
• Turbulence :Intensity – 5%
: Hydraulic dia – 5 mm
Thermal
Backflow Total Temp : 300K [Default]


c_out (Pressure outlet )
Momentum
• Gauge pressure : 0 Pa (open to environment)
• Turbulence :Intensity – 5%
: Hydraulic dia – mm
Thermal
Backflow Total Temp : 300K [Default]


wall wall
Momentum
• Stationary wall
• No slip

I am a student in the class report want to do vortex tube but still not familiar with CFX operation, have not used CFD, if I want to change K-epslion how to set in CFX，thank。
