Some notes on 3-dimensional turbulent boundary layer data and turbulence modeling
Abstract
Three-dimensional turbulent boundary layer experiments on the direction of the measured turbulent shear stress are summarized. Data indicate that turbulent shear stress magnitude and direction are considerably affected by flow three-dimensionality. History effects can dominate the turbulence development in the outer region of the boundary layer. Investigation of the pressure-strain term in the turbulence transport equations indicates that the large effects found in three-dimensional boundary layers can be explained, when assuming for the modeling of that term a negative correlation between the fluctuating static pressure and kinetic energy.
