This study investigates physics-driven design strategies for vortex generator arrays on aircraft aft-bodies. Using high-fidelity DES, we clarify how Counter-Rotating Pairs and Co-Rotating Arrays utilize distinct mechanisms, specifically dissipative mixing versus topological partitioning, to manipulate wake vortices and maximize pressure recovery.
