A study of the sensitivity of an incompressible turbulent boundary layer on the verge of separation
Abstract
Consideration is given to the sensitivity of turbulence models to small changes in the static pressure distribution for a boundary layer on the verge of separation. Also, the effect of these changes on the meanflow and turbulence quantities of an incompressible turbulent boundary layer with incipient separation is examined. The characteristic properties of steady turbulent boundary layers both on the verge of separation and with a long, shallow separation bubble are described. Changes in the characteristic flow quantities, such as skin friction, displacement thickness, and reverseflow parameter, are presented to demonstrate the sensitivity of the test boundary layers to changes in the upstream pressure distribution.
