Structure of Three-Dimensional Separated Flow on Symmetric Bumps

摘要

Surface mean pressures, oil flow visualization, and 3-velocity-component laser-Doppler velocimeter measurements are presented for a turbulent boundary layer (TBL) of momentum thickness Reynolds number, Re(theta) and TBL thickness delta over two axisymmetric and one symmetric bump. LDV data were obtained at one plane x/H = 3.26 for each case. Vortical separations on the leeside merge into large stream-wise mean vortices downstream. The near-wall flow.
