Theoretical and Empirical Studies of the Basic Structure of Turbulent Shear Flows, Including Separated Flows and Effects of Wall Curvature.

Abstract

Diffuser Flows, Detachment - Computation methods for planar, annular and conical diffusers and for compressible flow up to M - 0.9 have been completed. Methods for planar cases have been extended to include unsteady entry and free stream conditions. All methods are very fast and very accurate. Increased understanding of the physics of flow detachment has been realized and this understanding has been correlated and related to improved implications in computation. The increased understanding and improved correlation provides a basis for a 'stall-margin metric,' for inverse design procedures and for contour optimization.
