The Numerical Study of Flows over Blunt Bodies by Method of Integral Relations

Abstract

Systematic calculations over blunt bodies of simple shapes are carried out for two-dimensional and axisymmetric flows at high Mach number. Emphasis is placed on detachment distance and accuracy of results obtained by Method of Integral Relations. And the relation between the accuracy and uniform flow Mach number was investigated.
For flows at high Mach number, it was concluded that the sufficient accuracy was obtained even by the lowest approximation.
The study of flow patterns for two-dimensional and axisymmetric bodies made it clear thatthis method is more suitable for axisymmetric bodies than two-dimensional bodies in the flows at higher Mach number.
