A comparison of the results of interference and numerical determinations of flow density in the separation area
Abstract
Interferograms of supersonic flow past a free-flying blunt body with a disk attachement are presented, and the quasi-axisymmetric inhomogeneity is analyzed statistically to determine the radial profiles of the average density. Flow is then calculated numerically using a hybrid two-layer scheme with an isolation of a viscous mixing layer. A comparison of the interference and numerical profiles reveals certain inaccuracies in the numerical modeling of flow in the vicinity of the front shock wave. Possible refinements to the numerical method are proposed.
