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=10…
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…
Lift generation on a sphere through asymmetric roughness using active surface morphing
Rodrigo Vilumbrales-Garcia, Putu Brahmanda Sudarsana, Anchal Sareen
This study investigates a novel phenomenon of lift generation around a sphere by pneumatically manipulating its surface topology with an asymmetric roughness distribution. A compre…
Active flow control over a sphere using a smart morphable skin
Rodrigo Vilumbrales-Garcia, Putu Brahmanda Sudarsana, Anchal Sareen
Dimples on a sphere's surface can lead to significant drag reduction. However, the optimal dimple depth to minimize the drag varies with the Reynolds number (). In this study,…
