化学反応を含む圧縮流の数値計算jpnhttp://id.nii.ac.jp/1696/00043290/Technical ReportNumerical Calculation of Chemically Reacting Compressible Flow石黒, 登美子小川, 哲和田, 安弘Ishiguro, TomikoOgawa, SatoruWada, Yasuhiro航空宇宙技術研究所National Aerospace Laboratory(NAL)航空宇宙技術研究所特別資料 = Special Publication of National Aerospace Laboratory SP-9927361988-12A summary of our solver-code which is being developed for the purpose of analyzing chemically reacting compressible flows numerically is presented. The code solves the two or three-dimensional Reynolds time average complete Navier-Stokes equations including species transport equations, and has two strong points. The first point is that the system of governing equations for the flow computation contains a total mass conservation equation and transport equations of all species taking account of total mass conservation and impartial numerical treatment of every chemical species. Therefore, the correction of mass ratios of an species is made so that the summation of them equals to 1 after every time step integration. The second point is that the TVD difference scheme is used in order to capture strong discontinuous surfaces clearly and efficiently which are apt to appear in supersonic flow fields. Applying this solver, shock-induced chemically reacting flows and flow fields for the case of transverse sonic injection of H2 fuel into a supersonic airstream are analyzed numerically.0289-260xAN10097345https://jaxa.repo.nii.ac.jp/?action=repository_action_common_download&item_id=43296&item_no=1&attribute_id=31&file_no=1資料番号: NALSP0009005レポート番号: NAL SP-92020-01-28
