| 摘 要： | 根据速度和能谱测量以及湍斑实验,提出了湍流减阻时的弹性边层与LV 区流动的外边界层性质类似,均为非牛顿层流。在此基础上,对Virk 所提出的速度分布的三层结构模式作了重要修正.

| Abstract: | The similarity in flow characteristics between elastic sublayer of turbulent drag re-duction and outer sublayer of LV zone flow was indicated by velocity,spectrameasurements and turbulent spot experiments.Both of the sublayers belong toNon-Newtonian laminar flow.Based on the foregoing,a new scheme of mean ve-locity profile which is different from Virk's is presented in the paper. |
