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.
Most of us are familiar with the classic example of a liquid-gas moving contact line on a solid surface: a raindrop, sheared by the wind, creeps along a glass windscreen. The contact line's movements depend on the interplay ...

A trio of mechanical engineers at Seoul National University has found that the shape of a water jet dropped into a glass of water is the determining factor in the noise that results. In their paper published in the journal ...
Sharks in nature swim at high speeds in a deep ocean due to their high drag reduction ability. Water flows around the sharkskin become disrupted by staggered and overlapping microscale structures named denticles. In addition ...
