摘要

Incompressible, non-vortex-shedding bluff-body Flows and supersonic base-pressureflows are discussed from a unified viewpoint in which the aspect ratio of the near wake is determined from the balance of shear-stress and pressure forces on the near-wake boundary. The base pressure and drag are then determined from free-streamline theory. The analysis is incomplete, for want of sufficient information about conditions in reattaching supersonic turbulent shear layers. (Author).
