Cover Story: Micro-vortex generators (MVGs) play a crucial role in mitigating flow separation in supersonic boundary layers. This study utilizes large-eddy simulation (LES) to analyze flow structures in a Mach 2.5 boundary layer influenced by tandem MVGs with varying spacing, compared to a single-MVG reference case. High-fidelity numerical simulations reveal intricate vortex interactions, mutual cancellation, and heightened energy dissipation. Contrary to expectations, tandem MVGs reduce flow control effectiveness, underscoring a critical trade-off in optimizing MVG configurations for supersonic applications. View this paper
