Calculation of the effect of concentrated wall suction on a turbulent boundary layer using a second-order moment closure

摘要

The effect of suction, applied through a porous wall strip of finite streamwise length, on a turbulent boundary layer is investigated using a turbulence model, based on a second-order moment closure. Calculations are carried out at two Reynolds numbers and two suction rates. To allow for a pertinent comparison between the Reynolds numbers the boundary layer thickness and the suction strip dimensions are kept the same for all calculations.
