导出了轴对称障碍物绕流中小尺度湍流的快速畸变理论解。得到了速度协方差和欧拉时间尺度的一般公式,并对绕球流动的特殊情况进行了计算。文中还讨论了该流的大尺度极限。
A solution to the rapid-distortion theory for small-scale turbulence in flow round an axisymmetric obstacle is derived. General formulae for velocity covariances and Eulerian time scales are obtained and are evaluated for the particular case of flow round a sphere. The large-scale limit for this flow is also discussed.
