Design and evaluation of pulsed jet actuators network for active flow control on NACA-4412 profile

Résumé

The ongoing project (PERSEUS) is focused on the active flow control of the boundary layer detachment by means of a Pulsed Jet Actuator (PJA). The PJAs are to be implemented on a NACA-4412 profile fabricated at scale and tested in the wind tunnels capacities of UORL. This requires the miniaturization and redesigning of usual PJAs in order to fit the spatial and operational constraints of the mock-up. The workflow starts with a preliminary design of the PJAs with CFD simulations in order to estimate the performance in terms oscillatory frequency and average flow velocity at the outlet. Then the selected designs are fabricated with 3D printing and characterized by hot wire anemometry in order to compare with the numerical simulations. Finally the complete assembly of oscillators will be implemented in the wing airfoil for testing on the wind tunnel.
