On a transient disturbance in a flat-plate laminar boundary layer
Abstract
The evolution of a transient disturbance in a flat-plate boundary layer has been examined. The disturbance was produced by a jet impulse through a small hole at a supercritical Reynolds number. The evolution is characterized by a rapid, linear growth of a velocity excess region downstream of the disturbance. The growth of the velocity excess leads to the formation of an internal shear layer and the subsequent breakdown.
