タイトル（掲載誌）航空宇宙技術研究所特別資料 = Special Publication of National Aerospace Laboratory SP-10
一般注記The "rarefied gas numerical wind tunnel"with the universal code described using the null-collision direct-simulation Monte Carlo method is used for the simulation of the vortex shedding in dilute gas flows past an inclined flat plate at the incidence angle 45 degrees. 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.
