On The Turbulent 'Spot' in a Boundary Layer Undergoing Transition.
Abstract
Artifically initiated turbulent spots in a Blasius boundary layer were investigated experimentallly using hot wire anemometers. Electrical discharges initiated the spots which grew in all directions as they were swept downstream by the mean flow. Conditional sampling methods enabled the ensembling of data and yielded an average shape of the spot and the mean flow field in its vicinity. All quantities measured seem to be independent of the type of disturbance which generated downstream.
