Inlet boundary condition for transitional turbulence models

roozbehmousavi · October 13, 2015, 09:05

Dear all,

I would like to use a transitional turbulence model such as Transitional-SST for an internal flow simulation. The flow is developed through a channel connecting a high pressure and a low pressure chamber. As the flow is not turbulent at the inlet, which values should I set for the inlet turbulence intensity and turbulence viscosity? Is it OK if I set them nearly zero, i.e. ~1e-6?

Regards

Yes. You may want to use intensity & length scale if it is more convenient.
