Numerical solutions using the Hartree characteristic method for the propagation of spherical blast waves in a detonation gas are presented in the present paper. Two models have been studied, the reacting blast wave R-B-W model and the finite kinetic rate F-K-R model. For the R-B-W model, the present numerical solution is used as a reference to assess the accuracies and the domains of validity of the various existing analytical solutions i.e., quasi-similar method of Oshima, perturbation method of Melnikova and Sakurai and the density probile method of Porzel. Based on a blast wave model for a multiheaded detonation front, the present F-K-R solution is used to predict the transverse wave spacings.
