Investigation of the Use of Method of Integral Relations for Solutions of Strong Shock Wave Intake Diffusers

摘要

The internal flow fields of the two dimensional convergent wedge type, pitot type, and spike type diffusers with a strong attached unswallowed curved shock wave at their inlet is analyzed. The direct method of integral relations was applied to the inviscid equations of the subsonic internal flow in the diffuser for the general case of arbitrary wedge or spike angle and of arbitrary free stream Mach number. First order theory results are presented for a range of wedge or spike angles and Mach numbers. First order theory and experiment were compared at a Mach number of 3 for the case of a two dimensional convergent wedge diffuser.
