An Experimental Investigation of the Effects of Wires and Forward-Facing Steps on the Laminar-Turbulent Transition of a Sucked Boundary Layer

Résumé

While air traffic volume is projected to increase, the aviation industry is also faced with the need to reduce its fuel consumption for environmental sustainability, leading to a renewed interest in laminar flow control (LFC) research. One LFC technology consists in stabilizing the boundary layer using wall suction, most commonly through a micro-perforated suction panel or porous wall. Applying wall suction on a boundary layer increases its mean velocity profile curvature (and therefore its stability), and redistributes the disturbance energy closer to the wall where there is higher viscous dissipation. As a result, the growth of boundary layer instabilities is reduced and transition is delayed.
