Abstract

We self-consistently study the properties of the dissipative standing shock waves in an accrertion flow around a stationary black hole. We use analytical method to achieve our goal and identify an effective area in the parameter space spanned by the specific energy and the specific angular momentum which allows accretion flow to pass through shock having some energy dissipation. As the dissipation is increased, the parameter space is reduced and finally disappears when the dissipation is reached its critical value. We show the variation of shock location and compression ratio as a function of the specific energy and study them in terms of energy dissipation across the shock.
