Furler, Stuart Murray2017-12-102017-12-101973b1016235http://hdl.handle.net/1885/137435The problem considered was that of the behaviour of a non - equilibrium flow behind a shock wave supported by a convex curved body in a hyper- ­ velocity freestream . A simple gas model was assured, taking into account the dissociation only of asymmetrical diatomic molecule , whilst the temperature in the shock layer was assumed to be small compared with the characteristic temperature of dissociation . The curvature of the stream ­ lines produces a negative pressure gradient along a streamline and the effect of this pressure gradient upon the reaction was studied. An approximate analytic solution was obtained, which shows that properties along a streamline are consistent with the assumption that the reaction proceeds independently of the pressure gradient initially , and after a short distance the gas may be considered non - reacting and the properties given by perfect gas relationships. The result was verified both with exact numerical integration of the relevant equations , and with some experimental results from a hyper velocity nitrogen flow over a circular cylinder.[85] p.enGas dynamicsShock wavesGas flowChemical equilibrium197310.25911/5d70ebf80a1532017-11-22
