BC Profile with Turbulent Intensity
can i use turbulent intensity (%) as a profile boundary condition?
when i look at the "standard variable names" in CFX helper i only
see that i can specify k (turbulence kinetic energy) as a profile bc parameter.
if i use k in the profile BC, than CFX ask me for epsilon (turbulent dissipation rate). i dont have epsilon though....
thank you very much!
Turbulence intensity % just defines the turbulence intensity (k) as a function of flow velocity. It does not define the second variable required to specify the turbulence inlet condition. You will need to specify an epsilon, turbulence length scale, turbulence viscosity scale or some other independent turbulence parameter to define the second turbulence variable.
