Source Distribution of Turbulent Bursts During Natural Transition Final

摘要

The basic statistical properties of the wall pressure field associated with turbulent spots in a transition boundary layer have been measured on a large flat plate test fixture in the Anechoic Flow Facility at the Naval Ship esearch and Development Center. The measured statistical properties and the distribution of the turbulent spots on the plate surface are compared with a quantitative formulation of the transition process which was developed by Emmons. This paper considers the consistency between the predicted and measured statistical burst properties when two simple forms of the source-rate density function are assumed.
