Abstract:

The split-coefficient matrix (SCM) for solving inviscid flow over the asymmetric nose-cone is presented. According to SCM technique, governing equations are solved by MacCormack's second-order scheme in a predictor-corrector sequence. The present paper presents the numerical results of the flow field and aerodynamic characteristics over an asymmetric nose-cone.The accuracy analyses of the results are also given in this paper.
