We've all been sprayed by a shaking soaked pooch. Now their technique could be applied to washing machines.
Furry animals dry themselves off so well that machine designers are now studying the underlying physics.
A ratio of centripetal force and surface tension helps to explain how mammals shake themselves dry.
The findings could inspire better washing machines, dryers, spin coaters and other devices.
Wet dogs and other wet animals shake their bodies in such a precise, effective manner that washing machine designers are taking notice, according to a new study that is the first to explain the physics of animal self-drying.
In addition to better washing machines, the findings could lead to improvements to dryers, painting devices, spin coaters and other machines.
"It's surprising, but we still do not understand why washing machines work so well," co-author David Hu said. "The equations that govern the fluid motion inside them are too complicated to solve. In this research, we decided to look to nature to ask the question: 'How do we dry clothes effectively and efficiently?'"
