Tests of a proposed friction-factor equation have shown it to be accurate for calculating pressure loss in turbulent flow for a pipeline transporting a non-Newtonian fluid, such as most crude oils and ...

A sneeze. Ocean currents. Smoke. What do these have in common? They’re instances of turbulence: unpredictable, chaotic, uneven fluid flows of fluctuating velocity and pressure. Though ubiquitous in ...

While atmospheric turbulence is a familiar culprit of rough flights, the chaotic movement of turbulent flows remains an unsolved problem in physics. To gain insight into the system, a team of ...

Turbulence, famously described by Richard Feynman as “the last unsolved problem of classical physics”, pervades almost all natural and engineering flows. The century-old challenge of turbulence ...

The famous painting from Dutch post-impressionist Vincent van Gogh has sparked controversy among physicists. Two decades ago, a pair of physicists stood in a museum in Madrid contemplating the work of ...
