The Physics of Turbulent Boundary Layer Structures and Effects Due to Manipulation

Abstract

A summary of work conducted on a scanning LDV system, three dimensional mapping of burst and sweeps, and LEBU effects on ejections and bursts is presented. This followed by an in depth report on the three dimensional mapping of the bust structure. This study was conducted using an X- film probe to detect the burst and a three-component LDV to map the velocity field. Conditional sampling analysis showed a streamwise vortical structure with the downstream end inclined up from the wall. (jhd)
