Mechanisms of lift generation and drag invariance by asymmetric surface roughness on a sphere
Putu Brahmanda Sudarsana, Jagmohan Singh, Anchal Sareen
The mechanisms governing transverse force generation on a sphere with asymmetric dimpled roughness are investigated using wall-resolved large eddy simulation at $Re=U_\infty d/ν=1…

Wake Stabilization and Force Modulation via Surface Dimples on an Airfoil at Low-Reynolds-Numbers
Putu Brahmanda Sudarsana, Jagmohan Singh, Anchal Sareen
This study investigates the effect of surface dimples on the unsteady aerodynamics of a National Advisory Committee for Aeronautics airfoil (NACA0012) at a chord-based Reynolds num…
