This study investigates the impact of slat and flap configurations on aircraft wake vortex dynamics using the AIAA HiLiftPW-1 trapezoidal wing model. A Liutex-Omega vortex identification framework combined with connected component analysis enables precise extraction of vortex parameters, validated through hybrid RANS-LES simulations. Results demonstrate that slat deployment accelerates wing vortex formation and amplifies flow complexity at wing-body junctions, while flap span length critically governs merging patterns. Increased flap deflection enhances vortex concentration and delays dissipation, with merging chronology significantly influenced by fuselage-induced interactions. Proper Orthogonal Decomposition reveals energy redistribution mechanisms during merging, highlighting slat-induced suppression of streamwise energy decay. Although aerodynamic performance remains stable under configuration changes, vortex merging modes exhibit nonlinear sensitivity to high-lift adjustments. The study preliminarily establishes a predictive link between flap geometry and merging regimes, providing insights for wake management strategies. Future work will address mid-to-far-field vortex evolution under critical configurations.
