Ballistic Range Flowfield Measurements of the Hypervelocity Near Wake of Generic Shapes and Correlation with CFD (Computational Fluid Dynamic) Simulations

Abstract

This paper describes analytical and experimental research into the structure and properties of the near wake of generic shapes at supersonic flight conditions. Three axisymmetric model configurations were constructed and tested in the aeroballistic research facility at Eglin Air Force Base, Florida at Mach numbers from 3 to 5. Laser interferograms were taken of the near wake of the configurations at sea level conditions. Computational interferograms were then developed at identical conditions and were correlated against the experimental data. This correlation will help calibrate high speed CFD codes in this complex flow region. Keywords: Aeroballistics, Near wake; Recirculation zone; Interferogram.
