Outline
The numerical simulations were performed to study the standing detonation wave structure and performance induced by a supersonic inflow impinging on a cone. The variations of detonation wave structure and the pressure behind the wave at the different initial temperatures of inflow were analyzed. The results show that the ratio of pressure increase is enhanced along with the decrease of the initial inflow temperature, which is benefit from the improvement of propulsion performance of oblique detonation wave engine. At the higher initial inflow temperature, the detonation wave front shows a smooth shape, while at the lower initial temperature, the triple structures appear at the front. The lower initial temperature is, the more number of the serried triple points are. These triple points with higher pressure contribute to the pressure variations behind the standing detonation wave.
