The Birth of Open Separation on a Prolate Spheroid
Abstract
Results are presented to describe the laminar flow patterns around a prolate spheroid at angles of attack of 1, 2, 3, and 30 degrees and complement those obtained previously at 6 degrees. They were obtained by solving three- dimensional boundary-layer equations with a combination of standard and characteristic box methods and with a stability criterion to ensure numerical accuracy. Emphasis is placed on the nature of separation which , in agreement with experiment but contrary to some theoretical claims, is shown to be open for all angles of attack and to be coincident with a particular skin friction line. Keywords: Fluid mechanics, Boundary layers, Bodies of revolution, Crossflow, Singularity, Three-dimensional flows.
