Hirosaki Bunka Center), Hirosaki, Aomori, Japan, The reduced dissipation approach has been applied to AUSM-family flux functions of SLAU2 and AUSM(+)-up towards high resolution transonic buffet simulations on unstructured grids. In this approach, the dissipation term (of the pressure flux) in each flux function is locally controlled (0 < γHR < 1, γHR: dissipation coefficient) where a cell-interface orientation angle is small (i.e., cell geometry is nearly squared) and/or where flows are smooth, and the original methods are recovered otherwise (γHR =1). Numerical tests demonstrated that the proposed HR (High-Resolution) -SLAU2 achieved better resolution (while maintaining robustness) for a double shear layer problem (Mach 0.01) and decaying isotropic turbulence (Mach 6×10(exp(-4)), compared with the original counterparts (γHR =1) or an existing method (HR-Roe), whereas HR-AUSM(+)-up showed degraded resolution due to a large cutoff Mach number required for a stability reason., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530023018, レポート番号: JAXA-SP-14-010},
