Default Anyone used DES for Airfoil Analysis?
Posts: n/a
I am interested in capturing the onset of boundary layer transition and maximum CL for airfoils at Re 6 million and mach of 0.35 I have used the k-e and k-w models to predict aerodynamic coefficinets with lift and drag varying approximately 5%-7% over experimental data for an AOA range of 0-10 degress, for the case where the boundary layer transition has been fixed (with the k-w SST model). The case for free or natural transition using DES is the focus now, and i would be interested to know how others have studied this in particular the process of natural transtion.
