Entropy Layers

Abstract

The entropy layer on a blunt-nosed cone is analyzed, in view of the difficulties it produces in numerical computations. A rule is given to determine at what distance from the nose the entropy layer is a given fraction of the shock layer, for a given free stream Mach number. A simple and efficient way of computing flows with strong entropy layer effects is given. It involves inserting two streamlines representing loci of rapid changes in entropy derivatives, and forbidding differentiation across such lines.
