Researchers simulate bubble collapse near oscillating walls

Bubble dynamics plays a significant role in mechanics, chemistry, medicine, and biology. Understanding their interactions with the surrounding walls of the container is crucial for numerous applications, including cavitation ...

How to shelter from a nuclear explosion

There is no good place to be when a nuclear bomb goes off. Anything too close is instantly vaporized, and radiation can pose a serious health threat even at a distance. In between, there is another danger: the blast wave ...

Flying snakes help scientists design new robots

Robots have been designed to move in ways that mimic animal movements, such as walking and swimming. Scientists are now considering how to design robots that mimic the gliding motion exhibited by flying snakes.

Research explains basics of aerosol formation at the vocal folds

Very small exhaled droplets, so-called aerosol particles, play an important role in the airborne transmission of pathogens such as the coronavirus. Researchers in the field of fluid mechanics used a model to investigate how ...

Simulating the shear destruction of red blood cells

Many medical devices for treating heart failure generate nonphysiological shear flow. This can trigger the destruction of red blood cells after implantation of ventricular assist devices (VADs), artificial heart valves, vascular ...
