Default wake BC for airfoil C - Grid
Posts: n/a
hi everyone, I am trying to implement k-omega into a finite-difference code. Currently trying to solve airfoil problem but I am getting negative values of k, omega and turb. viscosity at the wake cut. Could you suggest me a remedy for the wake? what boundary conditions to implement for k,w,Mt and what to do for negative values of these turb. parameters? Thanks in advance..
