Interfacial flows is a research area focused on fluid motion in the presence of interfaces separating immiscible phases, such as liquid–gas or liquid–liquid systems, where interfacial tension, wettability, and curvature critically influence dynamics. It encompasses fundamental and applied studies of capillarity, Marangoni effects, thin-film dynamics, droplet and bubble motion, and interface instabilities under various driving forces (gravitational, inertial, viscous, or electrohydrodynamic). The field integrates continuum mechanics, interfacial thermodynamics, and multiphase flow modeling, often using advanced numerical methods and high-resolution experiments to elucidate transport, mixing, and pattern formation in systems ranging from microfluidics to large-scale industrial or environmental flows.
Our body contains an intricate system of tiny vessels through which blood, water and other molecules flow. When the size of the pipes shrinks to the nanoscale, where only a few molecules can fit side by side, the classical ...

Summer brings with it the sight of surfers moving seamlessly across wave crests, with ocean waters carrying them along coastlines. A team of scientists has now created a similar phenomenon—with small objects rather than surfers—that ...

When they reach the bottom of a soap dispenser, frugal handwashers might try adding water to the bottle to push out the last bit of soap. But usually, the water drills right through the soap and jets out an only slightly ...

Earth's ice is melting. As icebergs break away from glaciers and melt away, the fresh meltwater mixes into its saltwater surroundings. However, icebergs do not exist in isolation. In Greenland, for example, jammed collections ...

Heart to the left. Liver to the right. That's where you'll find these organs in a healthy human body, but surprisingly, in some people, the heart is on the right and the liver on the left. This normal or abnormal asymmetry ...

Water droplets have a unique ability: They can leap from a surface on their own. This can happen for a variety of reasons, such as when a surface repels water or when heat is involved, such as a water or oil droplet skittering ...
