摘要 本文研究了无限后掠平板三维边界层的横流不稳定性,证明行进波和定常波几乎同时失稳,且行进波比定常波更不稳定;关于三维边界层中小扰动增长方向的不同提法对后掠平板基本一致。 In the paper the crossflow instability of an infinite swept flat plate is investigated.It is found that the traveling waves and stationary waves are amplified simultaneously and the traveling waves are more unstable,the existing suggestions for the growing direction of the disturbances in three dimensional boundary layer flows are basically in agreement with each other.
