The aerodynamic performance of active flow control on wings using synthetic jets with zero net-mass flow is investigated. The study is conducted via wall-modeled large-eddy simulations using a finiteelement-based solver. The performance of synthetic jets is evaluated for the high-lift configuration of the JAXA Standard Model at realistic Reynolds numbers for landing Rec = 1.96 × 106 . The results show that, at high angles of attack, the control successfully eliminates the laminar/turbulent recirculations located downstream the actuator, which increases the aerodynamic performance. Our efforts illustrate the technology-readiness of large-eddy simulation in the design of control strategies for real-world external aerodynamic applications.
