There are several books in the extensive and varied literature on Turbulence that deal, in statistical terms and in the context of fluid dynamics, with the phenomenon itself, as well as its many ...

Flapping and soaring: The tips of pelicans' wings turn down when they fly near the surface of water. Aerodynamics experts are trying to understand why. (Courtesy: iStock/Aschen) For human-built ...

Anomalous scaling in turbulent fluid dynamics refers to the observed deviations from classical scaling laws, such as those predicted by Kolmogorov’s 1941 theory. In turbulent flows, energy cascades ...

Shock–turbulence interaction dynamics constitute a central theme in fluid dynamics research, where the interplay between shock waves and turbulent flows leads to rapid energy redistribution and ...

Abstract: We explore the potential for new reduced basis representations within current state-of-the-art Large-Eddy Simulation (LES) frameworks to more accurately predict key resolved-scale dynamics ...

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 ...

Turbulence, the splintering of smooth streams of fluid into chaotic vortices, doesn’t just make for bumpy plane rides. It also throws a wrench into the very mathematics used to describe atmospheres, ...

From blood spurting through hearts to winds buffeting cars, fluids swirl and tumble in complex ways that scientists struggle to understand. Now, a new means to efficiently depict fluid turbulence and ...

Our research efforts in Computational Fluid Dynamics (CFD) include high performance computing for compressible and incompressible flows, development of finite volume schemes for hybrid and generalized ...

A scientists is using ALCF resources to create high fidelity simulations of jet turbulence to determine how and where noise is produced. The results may lead to novel engineering designs that reduce ...
