A Numerical Determination of the Bow Shock Wave in Transonic Axisymmetric Flow about Blunt Bodies.

摘要

A numerical method is developed for calculating axisymmetric transonic flow about a blunt body. The bow shock wave location is of particular interest. A Rankine Hugoniot jump is applied at the shock while relaxation on the isentropic equation of motion is used between shock and body. The shock wave is adjusted by a Newton type iteration scheme. Results are given for a sphere in the Mach number range 1.62 down to 1.02.
