| 内容記述 | Chemical nonequilibrium and radiating flow in the stagnation region of a hypersonic blunt body is investigated in the merged layer regime. The coupling phenomena between nonequilibrium chemical reaction and radiation are studied for a multicomponent air mixture. The radiative energy transfer is simplified to the emission-dominated case. The basic model of the flow is described by the simplified Navier-Stokes equations based on the thin layer assumption. Using the concept of local similarity, the equations are reduced to a set of nonlinear, coupled ordinary differential equations. This set of equations is solved using a new numerical technique called SAR Method. Solutions are obtained for a blunt body flying at 10 km/sec and for a free-stream Reynolds number range of 500 to 5730. The results show that a strong coupling exists between the nonequilibrium chemical reactions and the radiation cooling effects, and that the radiative heat transfer to the body is considerably reduced due to the reaction dominated nature in the combined flow. The physical interpretation of these phenomena and the detailed behaviour of the flowfield are discussed. In order to develop the discussions of results in more general sense, the influence of the body nose radius on the behaviour of the flowfield is also investigated in the present paper. | |||||||||
