i want to know more about sensibility to finite freestream values in k-omega model . in advance, thank you

Many people say that the given free stream values (especially omega value) affect the solution. Some authors actually proved that fact. The prefer to use Baseline model of F.R. Menter, that blends k-omega and k-epsilon according to their performance; where they work best. Here are some useful references; - AIAA 93-2906 'Zonal Two Equation k-omega Turbulence Models for Aerodynamic Flows', Menter,F.R. , 24th Fluid Dynaics Conference - AIAA vol:30, no:6, Technical Notes, 'Influence of Freestream Values on k-omega Turbulence Model Predictions', Menter,F.R. - 'Turbulence Modeling for CFD' Wilcox,D.C., Chapter 4.5. 'Application to Free Shear Flows' - 4.5.3. Sensitivity to Free Stream Conditions.

thank you Emre

i have the wilcox's book, but i think Menter have explained more this problem, but i haven't his papers.

if someone can send me them, it will be helpful

thanks again for your reply

Search author Menter in the following website:http://www.sti.nasa.gov, you can find Menter's NASA report about your problems.
