描述了一种计算方法，用于快速和系统地预测和评估由于快速冲角变化或非定常俯仰或倾伏运动而引起的动态失速的发生。该方法结合了一个非定常，二维面板代码与二维边界层代码。面元代码提供了关于任意翼型进行规定运动的不可压缩、无粘流场。边界层代码计算层流，过渡和湍流制度。
A computational approach is described for the rapid and systematic prediction and evaluation of the onset of dynamic stall due to rapid incidence changes or unsteady pitch or plunge motions. The method combines an unsteady, two-dimensional panel code with a two-dimensional boundary-layer code. The panel code provides incompressible, inviscid flowfields about arbitrary airfoils undergoing prescribed motions. The boundary-layer code computes laminar, transitional and turbulent regimes.
