The Supersonic Flow Field Associated with a Conical Flame Sheet

Abstract

SummaryIt is shown that a pair of supersonic inviscid conical flow fields can exist on either side of a conical deflagration wave. The configuration is relevant to the base flow question and indicates how base drag may be alleviated by burning. Results of exact computations are presented as well as those derived from a slender-body theory.

“…One important aspect is to avoid the dissociation what is not possible if normal detonation waves (of Chapman-Jouguet type) occur. The Clarke model [1] where the detonation wave is separated in a shock wave and a deflagation wave is able to reduce the temperature. Here conical waves are used.…”
