Note on Sir Geoffrey Taylor's Criterion for the Rate of Boundary-layer Suction at a Velocity Discontinuity

摘要

Sir Geoffrey Taylor's criterion for the rate of boundary-layer suction at a velocity discontinuity is described, and is compared with experimental results obtained from boundary-layer explorations. It is found that, despite neglect of the pressure gradient due to the curvature of the flow, the criterion gives reasonable estimates of the suction quantity. On the other hand, close agreement with velocity profiles is only obtained when the pressure gradient is taken into account.
