Turbulence Properties

Hey,

I want to add turbulence intensity to my model.

First question is: Is "turbulentIntensityKineticEnergyInlet" the only way to do it in the k-epsilon-model?

Second question: Do I have to define "turbulentMixingLengthDissipationRateInlet" if I define "turbulentIntensityKineticEnergyInlet" or is it working when I have a fixedValue there instead.

Thank you!

Hi,

1. No. You can use whatever is appropriate for your model. zeroGradient, fixedValue, inletOutet (turbulentMixingLengthDissipationRateInlet is a child of the former).

2. No. You can use whatever BC you would like.
