[2], and Thasu and Duvvuri [3] have discussed high frequency oscillations in the near wake of circular cylinders at supersonic and hypersonic speeds and offered explanations regarding their origin with some experimental evidence. The present paper attempts to provide further insights into this problem. 收起
