The turbulent intensity is defined by Uturb/Uavg : ratio of the turbulent velocity with the mean flow velocity. I read everywhere than TI = 10% is already a quite turbulent flow, but of course,...

Thanks, but the residuals of the Turbulence parameters (k and epsilon) converge as well, reached 10-5, just as the other residuals. And my intuition is that a 10000% of turbulent intensity should...

Turbulent kinetic Intensity greater than 100%

Hello,

I am modelizing a gas flow through a Laval nozzle. (the flow become supersonic) with a 2D axisymmetric model. I started the simulation with a laminar flow to ease convergence. Then I want...
