| 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. |
