Abstract
Abstract : A basic theory of weak normal shock - turbulent boundary layer interactions is given for two-dimensional non-separating flows including mass transfer across the wall throughout the interaction region. Even small amounts of suction are found to significantly reduce both the streamwise scale and thickening effect of the interaction and delay the onset of separation. This is shown to be a consequence of the large mass transfer effect on the shape of the incoming boundary layer Mach number profile away from the wall. Parametric study results showing the influence of Reynolds and shock Mach number as well as mass transfer parameter on the interaction, plus favorable comparisons with various experimental data, are also presented.
