Superhydrophobic (SHPo) surfaces have been investigated vigorously since around 2000
due in large part to their unique potential for hydrodynamic frictional drag reduction without …

In this review, we discuss how superhydrophobic surfaces (SHSs) can provide friction drag
reduction in turbulent flow. Whereas biomimetic SHSs are known to reduce drag in laminar …

Digital holographic microscopy is used for characterizing the profiles of mean velocity,
viscous and Reynolds shear stresses, as well as turbulence level in the inner part of …

We study the flow above non-optimal riblets, specifically large drag-increasing and two-
scale trapezoidal riblets. In order to reach large Reynolds numbers and large scale …

Liquid-infused surfaces present a novel, passive method of turbulent drag reduction.
Inspired by the Nepenthes Pitcher Plant, liquid-infused surfaces utilize a lubricating fluid …

Turbulent skin-friction drag reduction with superhydrophobic (SH) longitudinal microgrooves
and riblets is investigated by direct numerical simulation (DNS), using lattice Boltzmann …

Devising effective methods to reduce drag forces is of great interest as these methods could
prevent the wastage of fuel and decrease carbon emission and the global warming rate …

In this work, inertial flows of a yield stress fluid in a channel equipped with a
superhydrophobic groovy wall are studied through numerical computations. Assuming an …

Superhydrophobic surfaces can retain gas pockets within their microscale textures when
submerged in water. This property reduces direct contact between water and solid surfaces …

We investigate the influence of statistical measures of surface roughness on the turbulent
drag reduction (DR) performance of four scalable, randomly rough superhydrophobic (SH) …
