It was found that the degree of interferences and the scale of turbulence vortex and the change in mixing behavior derived from the interferences were strongly affected by the initial arrangement of streamwise vortices. From these results, it can be concluded that the supersonic flow field and mixing as well as the combustion and thermal diffusion can be freely controlled by the operation of the arrangement of shock wave, shear layer, and streamwise vortex. There is some possibilities of realizing the mixing in the whole region of combustor by the streamwise vortices with plural struts., 資料番号: AA0000109008, レポート番号: NAL SP-28}, pages = {32--36}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {縦渦列を用いた超音速混合の制御}, volume = {28}, year = {1995} }
