Abstract:

Measurements, including all Reynolds stresses and triple products, have been made in three turbulent flows with imbedded longitudinal vortices generated by skewing of the mean flow secondary flow of the first kind i flow in an idealized wing-body junction, ii an isolated vortex in a two-dimensional boundary layer, and iii a vortex pair in a turbulent boundary layer. Selected results are presented spatial variations of eddy diffusivities and dimensionless modelling parameters are seen to be complicated. Author
