| Abstract: | NLE airfoil is the simplest and efficient drag reductiontechnique.This paper reviewed in detail on the predicting method ofthe transition on a swept wing and the selection of transition criterion.Meanwhile.simply discussed the influence of the pressure distributiontype and the turbulent level as well as noise on the transition.Finallysome conclusions are provided for designer's reference. |
