On Concave Bodies in Free Molecule Flow

Richard Schamberg

Expert InsightsPublished 1967

A summary of earlier work by Chahine, Pratt, Sparrow, and others on free molecule flow over nonconvex surfaces, and the presentation of their numerical results in an alternative form. This new form is more conducive to a physical understanding of the flow and to generalization to other geometries or surface interactions not yet analyzed in detail. Data on drag of concave surfaces are given. Free molecule flow over concave bodies has possible use in parachute-like drogue devices, high-altitude air collectors, propulsion induction systems, and pressure probes.
