Researchers at Imperial College London in the U.K. have solved a longstanding question in turbulence—the seemingly random changes in velocity and pressure that occur when a fluid flows fast enough—using supercomputers running simulations on graphics processors originally developed for gaming.
The researchers found a solution that allows them to check empirical models of turbulence against the "correct" answer, to determine how well they are describing what actually happens, or if that needs adjusting.
The supercomputer-created simulations allowed the researchers to find the exact parameters describing how turbulence dissipates in the flow, and determined various requirements that empirical turbulence models must satisfy.
