Nonsteady flows of an ideal dissociating diatomic gas
Abstract
Nonsteady flows of an ideal dissociating diatomic gas are investigated. The effects of molecular dissociation and recombination reactions on flow fields are discussed in detail. For equilibrium flows, the exact solution of the piston problem is constructed in the form of perturbation expansions in powers of the ratio of the temperature of the undisturbed gas to the dissociation energy. The numerical results are compared with those obtained in classical gas dynamics. The time and place of formation of the shock wave are determined when the piston moves into the pipe, and the loci of the shock wave in the xt-plane are also obtained.
