Abstract:
The developed active flow control strategy using spanwise arrays of multi-spark discharges is a highly flexible, efficient, and cost-effective approach offering inertia-free flow actuation and applicability to complex geometries without surface modification. Its development was possible due to the convergence of diverse sciences such as fluid dynamics, plasma physics, and biology that demonstrated the value of going beyond traditional disciplinary boundaries.
The obtained aerodynamic performance improvements (lift growth, drag reduction, stall delay) and the potential to control other physical processes, e.g., ignition, highlight the significant engineering impact.
