Numerical Computation of Inviscid Flow Around Nose Tip of Space Shuttle with NND Scheme

Abstract : The NND scheme presented by Professor Zhang Hanxin of the CARDC has been used in this paper to complete the following computations: the two- dimensional inviscid flow around the symmetric plane of the nose tip of the space shuttle; the three-dimensional inviscid flow around the nose tip of the space shuttle; the three dimensional inviscid flow around the axisymmetric indented body. Under the general coordinate system, the computation grids have been generated by algebra equations. The characteristic compatibility equations have been used to treat the shock and body surface boundaries, and there is a special treatment in translation of the coordinate system. Finally, the comparative computations have been completed using second order SCM schemes. The results of computation illustrate that the NND scheme used in this paper can avoid numerical oscillations and high resolution to shock-capturing
