Bayesian optimization and topographic exploration of drag-reducing dimples for aerodynamic surfaces
Sangjoon Lee, M. Erden Yildizdag, Haris M. Sheikh
Dimples offer a promising route to reducing drag on aerodynamic surfaces. However, whether such shallow concavities yield a net benefit depends sensitively on their topography, whi…
Airfoil optimization using Design-by-Morphing with minimized design-space dimensionality
Sangjoon Lee, Haris Moazam Sheikh
Effective airfoil geometry optimization requires exploring a diverse range of designs using as few design variables as possible. This study introduces AirDbM, a Design-by-Morphing…
Transient growth of a wake vortex and its initiation via inertial particles
Sangjoon Lee, Philip S. Marcus
The transient dynamics of a wake vortex, modelled as a strong swirling -vortex, are investigated with a focus on optimal transient growth driven by continuous eigenmodes associa…
Perturbation analysis of triadic resonance in columnar vortices: selection rules and the roles of external forcing and critical layers
Jinge Wang, Sangjoon Lee, Philip S. Marcus
The remarkable robustness of columnar vortices suggests the existence of fundamental constraints that prevent spontaneous disintegration. In this work, we investigate the weakly no…
