Abstract : Existing shadowgraph data and data from exact flow solutions for the bow-wave profiles generated by blunt-nosed bodies of revolution are studied with the objective of obtaining systematic descriptions of the wave profiles and their dependence on nose shape, Mach number, and total enthalpy. The waves are represented by power-law expressions of the kind suggested by blast-wave theory, and correlations of the constants in the equations are investigated. The study includes seven nose shapes, Mach numbers from 3.5 to 19.3, and total enthalpies from 400 to 8100 Btu/lb. (Author)
