A model for describing the hydrodynamics of crowds

Precise simulations of the movement and behavior of crowds can be vital to the production of digital sequences or the creation of large structures for crowd management. However, the ability to quantitatively predict the collective ...

Computer model predicts red blood cell flow

Adjacent to the walls of our arterioles, capillaries, and venules—the blood vessels that make up our microcirculation—there exists a peculiar thin layer of clear plasma, devoid of red blood cells. Although it is just ...

Simulating flow from volcanoes and oil spills

Some time around 37,000 BCE a massive volcano erupted in the Campanian region of Italy, blanketing much of Europe with ash, stunting plant growth and possibly dooming the Neanderthals. While our prehistoric relatives had ...

Liquid jets and bouncing balls combine for surprising results

A new study published in the American Institute of Physics' (AIP) journal Physics of Fluids reveals that the normal rebounding of a ball changes when it is partially filled with a liquid. Unlike an empty sphere or a solid ...

Turbulent flows in 2D can be calculated in new model

Turbulent flows have challenged researchers for centuries. It is impossible to predict chaotic weather more than a week in advance. Wind resistance on a plane or a car cannot be calculated precisely, since it is determined ...
