Spherical variable-energy blast wave in self-gravitating gas
Modified similarity method has been used to study the propagation of spherical-variable energy blast waves through a self-gravitating gas. For an energy inputEα=E0t4/3, whereEα is the energy released up to timet andE0 is a functional constant, the similarity solutions correct up to third approximation have been obtained. It is found that the effects of self-gravitational forces are of third order. An increase in the parameterA2 (characterising the gravitational field) increases the shock velocity.
