 April 10, 2007, 09:37 Turbulence Intensity and Length #1 airfoil Guest   Posts: n/a Hi All, May I know what is the criteria or assumption I have to follow for Inlet and Pressure boundary's Turbulence Intensity and Length? I know T.I is in percentage term but how do I decide the value? Does it varied from model to model? Thank you in advance!

Answer: The turbulent kinetic energy can be estimated as follows , where x is the velocity pulsation amplitude relative to the mean flow velocity V; The rate of the turbulent energy dissipation is estimated from , where μ is the dynamic molecular viscosity, N = 100 is a parameter. for details http://www.fv-tech.com/index.php?id=73
