Abstract
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.
