Hydrodynamic calculations of axisymmetric accretion flow

Abstract

Numerical calculations are performed for axisymmetric flow of inviscid ideal gas past a gravitating body. Cases based on two extreme boundary conditions on the surface of the body, i.e. a slippery condition on a rigid sphere and a maximum accretion condition on a hollow sphere, are computed and compared. The results are presented for Mach numbers of 0.6, 1.4, 2.4 and 5.0, and for the ratio of specific heats of 1.1, 4/3, and 5/3.
