From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their ...

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,” ...

Dr. Maute’s research group is developing novel approaches to topology and shape optimization for nonlinear structural and coupled multi-physics problems, such as fluid-structure interaction and ...

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, ...

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, ...
