Abstract : Near-equilibrium and near-frozen one-dimensional inviscid flows downstream of an initial station at which the flow is in equilibrium have been examined by means of perturbation analyses. The near-equilibrium analysis requires the application of boundary layer techniques. The near-frozen analysis is of standard type. It is demonstrated that both types of flow behave in a frozen manner near the initial station. However, the near-equilibrium flow quickly approaches the equilibrium behavior. Examples have been presented for both cases utilizing a dissociating model gas after Lighthill. Representative numerical results are included. (Author)
