| 内容記述 | A parabolized Navier-Stokes code was used to calculate laminar crossflow separation on a simple body of revolution. Convergence lines were defined as lines on which skin-friction lines converge and were visually determined from the computed skin-friction patterns. These convergence lines were shown to be limit lines and not envelopes. Examination of crossflow cuts of streamtubes which encircled the body indicated that crossflow separation (defined by a fold in the streamtube) began after the onset of negative crossflow velocities but before a convergence line could be determined from the skin-friction patterns. There were no rapid changes or extrema in the pressure, skin-friction, vorticity, or flow-angle distributions that indicated where separation occurred. Instead, crossflow separation developed gradually and involved an extended region of the surface. |
