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, ...

Vortex is a natural fluid phenomenon that is often of great consequence in almost any practical flow, such as shear layers, ...

From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their flow properties change depending on how much force is applied, but the ...

Fundamental constants: a minimum value of viscosity has been calculated by Kostya Trachenko and Vadim Brazhkin (Courtesy: iStock/3quarks). Viscosity is an everyday phenomenon recognizable in the ...

If you mix cornstarch and water in the right proportions, you get “oobleck”: something that seems not-quite-liquid but also not-quite-solid. Oobleck flows and settles like a liquid when untouched, but ...

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: They showed that for the simplest ...

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 ...

You spin me round: Two spinners inside a circular container are surrounded by liquid containing bubbles that help to visualize the flows. The left spinner is actively driven to rotate with a motor ...

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 ...
