摘要: 用高阶精度的紧致差分方法,对低速的随时间发展的二维可压缩H-2/O-2混合层流动编制了直接数值模拟的计算机程序,对雷诺数Re为400、来流马赫数Ma分别为0.4(上部的H2)和1.57(下部的O2)的H2/O2亚跨超声速混合层流动进行了计算,得到了相应的计算结果,并对结果进行了分析和研究.Abstract: The present work uses high order accuracy compact difference scheme and composites the computer code for 2-dimensional compressible low velocity H2/O2 mixing flow evaluating with time growth. Computation for subsonic, transonic and supersonic H2/O2 mixing flow with Reynolds number being 400 and Mach number being 0.4 (upper part H2) and 1.57 (bottom part O2) has been done and obtained computation results. The computation results are analyzed and studied.
