The results obtained for the freestream Mach number M infinity =0.7 and Knudsen numbers Kn infinity =1/60 and 1/200, for which the freestream Ryenolds numbers Re infinity =69 and 230, respectively, clearly show the wortex shedding in the wake region of the plate. The Strouhal number is about 0.2, which is rather larger than about 0.15 under continuum (incompressible) flow conditions. It is also found that the well-defined vortex structure disappears at rather small Knudsen number Kn infinity intinity (asymptotically) greater than 0.1 for M infinity =0.7 or at rather small Mach number M infinity intinity (asymptotically) greater than 2 for Kn infinity 1/60., 1/60., 資料番号: NALSP0010037, レポート番号: NAL SP-10}, title = {希薄気体数値風洞 V.斜め平板後流渦}, year = {1989} }
