摘要：
An engineering prediction method to calculate vortex shedding from noncircular forebodies with sharp chine edges in subsonic flow at large incidence angles is presented. The forebody is represented by two- and three-dimensional singularities, and the lee-side vortex wake is modeled by discrete vortices in crossflow planes along the body. The computational procedure is described, and comparisons Of measured and predicted surface pressure distributions and predicted flowfield vectors are presented to illustrate the method.
