Ants Avoid Traffic Jams by Giving Up
Both ants and traffic are well-connected to fluid dynamics, even if they are not, strictly speaking, fluids. As it happens, ant traffic has interesting implications not only for human transit Keep reading
Meteoroids
Meteoroids are debris from earlier eras in our solar system. They can be leftovers from planets that never formed or remains of ancient collisions. When these bits rock and metal Keep reading
Sheep as a Fluid
Not all fluids are, well, fluid. Traffic, flocks of birds, ants, and even sheep can behave like fluids. This video shows an aerial perspective on sheep being herded, and despite Keep reading
Shock Waves in Flight
Schlieren photography allows visualization of density gradients, such as the sharp ones created by shock waves off this T-38 aircraft flying at Mach 1.1 around 13,000 ft. Although shock waves are Keep reading
Traffic Fluid Dynamics
What does traffic have to do with fluid dynamics? Rather a lot, actually! Many parallels exist between traffic and compressible fluid flow. One such example, the concept of a shock Keep reading
Blast Waves
[original media no longer available] Watch closely in this high-speed video of a bomb exploding and you will see the spherical blast wave moving outward as a visual distortion. The Keep reading
Shock Waves
Flow visualization really can be considered a form of art. Though we fluid mechanicians are looking for physics, we’re quite aware of the beauty of what we study. The clips Keep reading
Shock Waves From a Gun
Often fluid motion is invisible to the human eye. Researchers use techniques like schlieren photography to make changes in fluid density apparent. In this high-speed schlieren photo, an AK-47 is Keep reading
