Calculation of the Flow Fields around a Series of Bi-Conic Bodies of Revolution Using the Method of Characteristics as Applied to Supersonic Rotational Flow

摘要

The flow fields around a series of bi-conic bodies of revolution placed in a supersonic air stream were analyzed using the method of characteristics as applied to rotational flow. Calculations were carried out for three different cone combinations (25 - 40 degrees, 20 - 40 degrees, 25 - 35 degrees) associated with various free stream Mach numbers. The results were used in designing a diffuser inlet. A study was made of the overall effects produced by rounding-off errors, varying the size of the mesh, and disregarding the entropy term. Some tables and graphs are included. (Author)
