REVIEW - ADVANCES IN 3-DIMENSIONAL TURBULENT BOUNDARY-LAYERS WITH EMPHASIS ON THE WALL-LAYER REGIONS (DATA-BANK CONTRIBUTION)

Current information concerning three-dimensional turbulent boundary la yers is discussed. Several topics are presented including (i) a detail ed description of eleven experiments published since 1990. In nine cas es cross flows ave controlled by pressure gradients imposed from the f reestream, but in two cases the cross flows are wall-shear-driven. The other topics include (ii) art examination of state of the art in meas urement techniques; (iii) a look at some issues and ideas in turbulenc e modeling; and (iv) an introduction to new work on the visualization and description of quasicoherent structures (high/low-speed streaks an d turbulent vortices) in three-dimensional turbulent boundary layers.
