The scheme is also recognized as an improved Advection Upwind Splitting Method (AUSM) where a slight numerical overshoot immediately behind the shock is eliminated. The proposed scheme has favorable properties, that is, high-resolution for contact discontinuities, conservation of enthalpy for steady flows, numerical efficiency, applicability to chemically reacting flows. In fact, for a single contact discontinuity, even if it is moving, this scheme gives the numerical flux of the exact solution of the Riemann problem. Numerical experiments indicate no oscillation and robustness of the scheme for strong shock/expansion waves. Higher-order extension is also discussed.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
