Measurements and a model for convective velocities in the turbulent boundary layer
A physical model is presented which describes convective velocities within a flat plate turbulent boundary layer. A production zone concept similar to that which Kline has reported with his visualization techniques is used as a basis for the physical model. The production zone concept employs the idea that packets of turbulent fluid are generated near the viscous sublayer. These packets are found to be discernible from the mean motion and may move either outward from the production zone or inward depending on their circulation relative to the fluid surrounding the packet. The packets are predicted ...
