Application of synthetic jets actuators in wing-pylon junction area to improve the high lift performances
Original language description
Synthetic jets actuators that produce a zero net mass flow rate have been locally applied at the pylon-wing junction to suppress the high-lift penalties caused by the closely coupled engine integration. The high fidelity numerical simulations utilizing unsteady Reyn-olds-averaged Navier-Stokes have been performed to simulate this problem. A wind tunnel model representing a 2,5D wing with pylon, nacelle and deployed high-lift devices is used for this study. Active flow control applied at the wing-pylon junction area can prevent the larger flow separation on the wing behind the nacelle caused by the slat cutback, increase the lift and to postpone the stall angle by interaction of the vortices from the SJA with vortices dominating this region. The performed unsteady CFD simulations demonstrate the possibility locally affect the flow by utilization of AFC. The geometrical setup of the actuators and the flow variables (blowing coefficient, actuation frequency) have been varied, as well. Two different shapes and positions of the nacelle's strike have also been considered during the simulations. The positive effect of the application of the SJA on maximum lift and stall angle has been observed .
