What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at ...

Abstract: Topology optimization has emerged as a promising and powerful approach to design engineered materials and components that utilize the ability of advanced manufacturing methods to realize ...

Physics of Fluids is a peer-reviewed monthly scientific journal on fluid dynamics, published by the American Institute of Physics with cooperation by the American Physical Society's Division of Fluid ...

We continue our exploration of fluids and fluid dynamics. We continue our exploration of fluids and fluid dynamics. How do fluids act when they're in motion? How does pressure in different places ...

At some point, most people have found themselves holding a tilted carton of milk or bottle of cooking oil, patiently waiting for the last drops to drip out. Now, physicists at Brown University have ...

The team’s theoretical calculations were largely supported by the results, and showed it’s all about the viscosity. Water reached the 90 percent mark in only a few seconds. Meanwhile, cold maple syrup ...

Computational fluid dynamics (CFD) is a branch of physics that utilizes numerical methods and algorithms to analyze and predict the behavior of fluids and gases under various conditions. This field ...

University of Chicago physicists have succeeded in creating a vortex knot—a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, ...

A college student in Switzerland says he’s solved a 100-year-old physics problem. The question is about an air bubble trapped in a very narrow tube of liquid, where the bubble appears to be “stuck,” ...
