Direct Numerical Simulation on 2D H2/O2 Mixture and Flow
【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H2/O2 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 H 2/O 2 mixing flow evaluating with time growth. Computation for subsonic, transonic and supersonic H 2/O 2 mixing flow with Reynolds number being 400 and Mach number being 0.4 (upper part H 2) and 1.57 (bottom part O 2) has been done and obtained computation results. The computation results are analyzed and studied.
