A length-scale correction recently developed for the SSG/LRR-ω Reynolds-stress model is applied to the flow around airfoils near maximum lift and the transonic flows around a wing and a generic aircraft with shock-induced separation. The length-scale correction is active only in regions of separation. It reduces the predicted maximum lift of airfoils by widening the separation bubble at the trailing edge, and predicts an increased size of shock-induced separation regions.
