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 ...

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 ...

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 ...

Subscribe to our newsletter for the latest sci-tech news updates. In a study published in Physics of Fluids, the researchers used the Navier-Stokes equations—the bedrock math of fluid flows—and a few ...

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,” ...

Figure 1. A faulty flame disperser may cause the coils adjacent to the flame to absorb more heat energy than optimally designed. February 15, 2022 Heat transfer fluids are often taken for granted, ...

It's near the start of a new semester of physics. Many faculty are working on their plans for introductory physics courses. How many tests should there be? What about homework? Do I want to cover ...

During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ ...
