Artificial stomach reveals fluid dynamics of food digestion

In efforts to fight obesity and enhance drug absorption, scientists have extensively studied how gastric juices in the stomach break down ingested food and other substances. However, less is known about how the complex flow ...

Darker-winged birds have better flight performance

Many seabirds evolved dark wings, independent from each other. New research shows that these darker wings heat up more and that this heating up increases the efficiency of flight in birds. Furthermore, the study confirmed ...

A detailed simulation of air flow after sneezing

By the beginning of April 2021, the number of people infected during the COVID-19 pandemic had risen to more than 130 million people of whom more than 2.8 million died. The SARS-CoV-2 virus responsible for COVID-19 is transmitted ...

Harnessing sound for health

When a person develops a kidney stone or a gall stone—hard accumulations of minerals and other compounds created by the body—they can experience a great deal of pain and discomfort. In more advanced cases, these stones ...

How the growth of ice depends on the fluid dynamics underneath

Researchers of the Toschi group of Eindhoven University of Technology think the water phase change problem with considering the water density anomaly is of great importance relating to common natural phenomena. Their research ...

Cloud simulations get a dose of realism

A cloud simulation that captures the development and evolution of clouds based on atmospheric physical processes is more accurate than other models.

Keeping it fluid: Probing how fluids behave in weightlessness

NASA astronaut Victor Glover installs the Fluid Dynamics in Space experiment, or Fluidics for short. Fluidics is the black cylinder pictured in the foreground of the European Columbus module of the International Space Station.
