Institution National Aerospace Laboratory NLR Date 1967-10-04 Abstract An accurate inverse method for the numerical computation of the supersonic flow around a blunt body, on the presupposition of ideal gas properties, is presented. By a suitable transformation the field under consideration is mapped on a rectangular strip. Integration of the equations of motion in the transformed domain is performed by simultaneous application of a third order predictor-corrector process in the subsonic part, and the method of characteristics in the supersonic part of the field. Numerical instabilities encountered are discussed and a smoothing technique for suppressing them is indicated. The results obtained are compared with results from literature, The merits of the one-strip direct approach, first proposed by Belotserkovskii for the blunt nose problem, are investigated. Computational results are compared with those obtained by other methods, in particular with respect to accuracy and computer time, giving an idea of the feasibility of the one-strip method.
