tstorm Member Join Date: Apr 2009 Posts: 78 Rep Power: 17	The k-e and k-w models have the option for a user-defined turbulent viscosity. Does anyone know if that turbulent viscosity is dynamic viscosity or kinematic viscosity? The difference of course is just a factor of density, which is nearly 1 for air in SI units, so the difference is small. Still, I don't know which it should be.
