Multiphase flows as a research area focus on the physics, modeling, and numerical simulation of flows involving more than one thermodynamic phase (e.g., gas–liquid, liquid–solid, gas–solid, or gas–liquid–solid systems). The field investigates interfacial dynamics, phase distribution, momentum, mass, and heat transfer between phases, and the onset of instabilities and flow regime transitions. Research emphasizes constitutive modeling (e.g., Euler–Euler and Euler–Lagrange frameworks), closure relations for interphase forces and turbulence, high-fidelity experimental diagnostics, and advanced computational methods to predict and control multiphase behavior in applications such as energy systems, chemical reactors, and environmental flows.
Raindrops form inside clouds when tiny particles of water collide and stick together, forming larger droplets that eventually fall to Earth. This process is hard to model accurately, with current approaches either imprecise ...

Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...

Ultrasound-based irradiation of rock formations has attracted considerable attention as a technique for enhancing heavy-oil (high-viscosity crude oil) recovery from deep underground reservoirs. However, a unified theoretical ...

A brown mass—a mixture of water, boulders and fine matter—plows through the landscape. The mountains wash more than a thousand lorryloads of material into the valley on a fairly regular basis, causing damage in excess of ...

When rockets fire into space, the insides of their engines become an extreme environment where temperatures soar and tiny particles are thrown around at hypersonic speeds. These particles behave in ways that break long-held ...

Whether the dust borne on the violent winds of a tornado or the sugar grains in a swirled cup of coffee, the behavior of particles carried along in turbulence is subject to some similarities—all of them difficult to predict ...

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 ...
