Flow Visualization Study of High Supersonic Flow Past a Blunt Cylinder-Cone FlareBody

摘要

Visualization is one of the trends in experimental flow research. It is aimed atthe improvement of the qualitative understanding of the flow physics and supports attempts to obtain a sound basis for modeling complex flow phenomena. In the article viscous interaction effects in the high supersonic flow are investigated experimentally around a generic re-entry body (cylinder-conical flare) at incidence using various flow visualization techniques: short exposure spark-shadowgraph, surface oilflow, holographic interferometry. Interesting features revealed by the surface flow topology, separations and shock-shock interactions are discussed.
