Fragmentation of bubbles and droplets in turbulence produces a dispersed phase spanning
a broad range of scales, encompassing everything from droplets in nanoemulsions to …

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

Fluid turbulence is commonly associated with stronger drag, greater heat transfer, and more
efficient mixing than in laminar flows. In many natural and industrial settings, turbulent liquid …

For centuries, bubbles have fascinated artists, engineers, and scientists alike. In spite of
century-long research on them, new and often surprising bubble phenomena, features, and …

Deposition of wax is considered one of the most significant culprits in transporting petroleum
crude oils, particularly at low temperatures. When lowering pressure and temperature during …

Nowadays, one of the biggest concerns in the world is increasing the CO 2 emissions and
global warming due to the over-consumption of fossil fuels. In addition, under the intense …

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 …

We have developed a new power-saving device to reduce the drag of a ship's hull using
small bubbles. The device reduces the energy required for bubble generation. The device …

In the maritime industry, the injection of air bubbles into the turbulent boundary layer under
the ship hull is seen as one of the most promising techniques to reduce the overall fuel …

This review explores a variety of techniques that utilize air injections beneath a vessel's hull
to reduce drag and consequently improve energy efficiency. It focuses on the methodologies …
