Bat flight model can inspire smarter, nimbler drones

Bats are among nature's best flyers—able to fly for long periods of time, maneouvre in mid-air with pinpoint precision and get into some very tight spaces. However, scientists have not fully understood exactly how bats ...

Simulating turbulent bubbly flows in nuclear reactors

Inside nuclear reactors, boiling water, bubbles, and turbulent flows affect safety and efficiency. For many years, modeling turbulent bubbly flows was a challenging, time-consuming problem. Researchers were largely limited ...

Upscaling turbulence for better laboratory studies

Turbulence in oceans, in the atmosphere or in industry is billions of times stronger than in lab experiments. Simply upscaling the lab results is not an option. Theoretically, however, there is a regime of turbulence in which ...

Electromagnetic water cloak eliminates drag and wake

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while simultaneously helping it avoid detection.
