An Approximate Analytical Model of a Jet Flow with Mach Reflection and Pulsed Energy Supply at the Main Shock

The supersonic flow of a reactive gas mixture with Mach reflection oblique shocks and pulsed energy supply at the stem is considered within framework Chapman–Jouguet theory. An approximate analytical model proposed that quickly determines shape size shock-wave structure as well parameters in various regions. As an example application model, “first barrel” highly overexpanded jet air-methane high velocity, studied. Flows hydrogen–air hydrogen–oxygen mixtures were also for comparison preceding numerical results. height triple point determined presence change chemical composition isobaric main shock.
