Drag reduction plays an important role in improving the efficiency of fluid transport and
reducing the energy consumption of transport vehicles. The essential feature of bubble …

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 …

Superhydrophobic surfaces have significant applications in industrial and chemical fields.
However, their current mechanical stability and underwater durability are insufficient, limiting …

We numerically investigate the pressure drop reduction (PDR) performance of
microchannels equipped with liquid-infused surfaces, along with determining the shape of …

This study experimentally investigates the entry of hydrophobic/hydrophilic spheres into
Newtonian and Boger fluids. By considering solution of 82% glycerin and 18% water and …

The formation of a stable-streamlined gas cavity following the impact of a heated Leidenfrost
sphere on a liquid surface or a superhydrophobic sphere on water is a recently …

In this work, we reported a kind of deflecting air cavity generation strategy by controlling the
superhydrophobic (SHB) area occupancy and the impact angle of water entry. The influence …

A steel ball with a density higher than that of water can bounce on a water surface when
heated to a temperature well above the Leidenfrost point. In this letter, an experiment is …

Formation of a splash crown and a cavity following the impact of a sphere on a body of liquid
is a classical problem. In the related problem of a droplet splashing on a flat surface, it has …

It is well-known that using passive enhancement techniques (such as grooves, dimples,
textures, and vortex-generators, and to name but a few) plays an important role in changing …
