| Abstract | Wall suction has been used extensively to reduce the growth of laminar boundary layer disturbances, such as Tollmien-Schlichting waves, cross-flow vortices and, more recently, Klebanoff modes, namely unsteady streamwise-elongated low-frequency disturbances generated by free-stream vortical perturbations. Wall suction has resulted in a delay of transition to turbulence with major benefits, such as reduction of viscous drag, noise, and fuel consumption.The central aim of the proposed work is to apply wall suction to attenuate the intensity of Klebanoff modes arising in swept-wing laminar boundary layers due to free-stream turbulence. These flow structures have never been studied over large scale aerodynamic bodies, despite their vast importance in numerous industrial and technological applications, such as the design of aircraft wings and turbine blades. The effects of wall suction have not been investigated for these technologically relevant flows. A reason for the dearth of works is the extreme difficulty in predicting and controlling such flows.The problem will be tackled by a combination of mathematical and numerical techniques. The proposed approach will offer a fast and numerically robust toolkit in line with the long-standing effort of the fluid mechanics community to control pre-transitional flows in an efficient manner | |
