If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

Researchers at Penn, led by Physics and Astronomy professor Arnold Mathijssen, have discovered ways to achieve quality coffee extraction using fewer beans. Published in “Physics of Fluids,” the ...

Gears have been around for thousands of years, with the first records dating back to 3000 BC. While they have advanced over ...

The first ever camera footage from inside a centrifuge has revealed a new mystery in the physics of fluids. A centrifuge is a standard piece of laboratory equipment that spins fluid samples at high ...

Cracked it: Fluid-based screen protectors need to absorb an impact as the system deforms. New research shows that simplifying the geometry of the system can be used to optimize the fluid. (Courtesy: ...

Rheology, high-speed imaging, and velocimetry combined to characterize how some roller-based nozzles perform so well with non ...

In a significant advance for semiconductor manufacturing, mechanical engineers created a simulation that makes it easier to choose environmentally friendly water jet and underwater ultrasound ...

A real-life forensic puzzle inspired researchers to explore the physics involved, and in Physics of Fluids, they present theoretical results revealing an interaction of the incoming vortex ring of ...
