This visualization shows moderately large pressure fluctuations within a 35-trillion-grid-point turbulence simulation, including 5x and 25x zoom-in views. The negative fluctuations organize into ...

Data Assimilation (DA) is an important mathematical method for predicting turbulent flows for weather forecasting. However, the origins of the critical length scale, a crucial parameter in this method ...

How much stress do pipes undergo when a liquid flows through them, and how does it depend on the degree of curvature of the pipe? Bends in pipes are different than their straight sections because, in ...

Turbulent flows are characterised by chaotic, multiscale motion that profoundly influences engineering, geophysical and biological systems. Direct numerical simulation (DNS) resolves all relevant ...

Anyone who has flown in an airplane knows about turbulence, or when the flow of a fluid — in this case, the flow of air over the wings — becomes chaotic and unstable. For more than a century, the ...

THE downstream component of the turbulent velocity has been recorded in a sea-water channel with a Reynolds number, based on the depth, of 4 × 10 7. The measurements were made near the southern end of ...
