While current flow control applications are mostly based on trial-and-error procedures, which are time and resources consuming, the methodology developed in this proposal will pave the way to a new approach to control system optimization.
This project therefore aims at developing more efficient Pulsed-Jet Actuators (PJAs), on the basis of fluidic oscillators and at computing their optimal characteristics (size, aspect ratio, blowing velocity and pulsing frequency) using a sensitivity-based approach which relies on high-fidelity numerical simulations. Our modus operandi is therefore based on a multidisciplinary approach targeting actuator optimization for flow-separation control by combining different state of the art technological advancements in optimization of PJAs for flow-separation control.
PERSEUS is built on the expertise gathered within the consortium in fluidic oscillators PJAs design, manufacturing, and ground testing (INSA), high-fidelity numerical simulations of compressible flows (ENSAM) which is fully supported by experts in fluid flow optimization for active control of separated flows (ENSAM/UORL), and wind-tunnel model design and testing (PRISME/ICA). Our interdisciplinary approach allows for determining the most effective control strategy and thus provide an optimal solution to maximizing the efficiency of PJAs for flow-separation control.
The main expected outcomes of the PERSEUS project are the following
Develop advanced and more efficient PJA technology
Contribute to optimization methods for fluid flows and numerical simulations
