THE BLAST-HYPERSONIC FLOW ANALOGY BASED UPON OSHIMA48S QUASI-SIMILARITY MODEL
Abstract
The quasi-similarity model of Oshima was applied to the blast-hypersonic flow analogy, and comparisons were made with other blast analogy solutions, real gas characteristic solutions, and experiment. The shock shape is no better predicted by the quasi-similarity model than by other blast analogy solutions. Hemispherecylinder surface pressures near the juncture of the nose and afterbody are better predicted by the quasi-similarity model, and the method yields the correct asymptotic value far downstream. The radial density distribution in the shock layer is well predicted over a small region of a hemisphere-cylinder. (Author)
