Effect of Slip on Flow Past Superhydrophobic Cylinders
Slip on Flow Past Superhydrophobic Cylinders
2014/10/23
Superhydrophobic surfaces are a class of surfaces that have a microscale roughness imposed on an already hydrophobic surface, akin to a lotus leaf. These surfaces have been shown to produce significan...
DRA REDUCTION IN TURBULENT FLOWS OVER MICROPATTRNED SUPERHYDROPHOBIC SURFACES
DRAG REDUCTION IN TURBULENT MICROPATTERNED SUPERHYDROPHOBIC SURFACES
2014/10/23
Periodic, micropatterned superhydrophobic surfaces, previously noted for their ability to provide drag reduction in the laminar flow regime, have been demonstrated capable of reducing drag in the turb...
Simulations of Turbulence over Superhydrophobic Surfaces
Turbulence Superhydrophobic Surfaces
2014/10/23
Significant effort has been placed on the development of surfaces which reduce the amount of drag experienced by a fluid as it passes over the surface. Alterations to the fluid itself, as well as the ...
