AbstractReal gas effects of compressibility, vibrational excitation, dissociation, ionization and electronic excitation are taken into account in blast wave formulation. Residual property concepts, as well as those of equilibrium quantum statistical thermodynamics, are utilized to relate the different microscopic internal energy excitation levels to macroscopic thermodynamic properties. Jump conditions across the shock front are then evaluated and a non-self-similar quasi-similar solution is obtained for the adiabatic point explosion problem. From the results it appears that temperature profiles are affected most by the real gas properties of the medium. Some of their effects are evident in density profiles, while pressure and particle velocity are relatively unaffected. Finally, the shock front decays slower than in the perfect gas case, especially during the initial stages of propagation.
