This emulates the approach in wind tunnel experiments, where the models are tripped using sand paper, V disturbances, etc. In such wind tunnel tests the transition location is prescribed, and the freestream turbulence intensity is very low. The idea is to have a “canonical” turbulent boundary layer, developing in the most controlled way in order to study the effects of turbulence. Therefore, in our wing simulation turbulence is also zero at our boundaries.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Regarding the use of Fluent data in Nek, could you give us some more information about your setup? Which RANS model are you using, and is it time-dependent?
