Modification of Ninth-Order Weighted Essentially Nonoscillatory Scheme for Mixed Subsonic/Supersonic Flow
T HIS Note describes a modification to the high-order-accurate weighted essentially nonoscillatory (WENO) scheme implementation byGross and Fasel [1,2]. Themotivation behind this effort was to have a high-order-accurate discretization for the convective fluxes that works equallywell for subsonic and supersonicflows. The schemes described in this Note are based on schemes by Jiang and Wu [3] and Balsara and Shu [4]. In [2], we discussed a procedure for constructing high-orderaccurate upwind schemes. We suggested reconstructing the flow variables at the left (L) and right side (R) of the i 1 2 interface using high-order-accurate WENO approximations [3,4] and to employ the Roe scheme [5],
