Sentences with phrase «turbulent fluids»

According to new research led by Philip Marcus of the University of California, Berkeley, and reported in Physical Review Letters in August, vortices in turbulent fluids spontaneously replicate themselves by drawing energy from shear in the surrounding fluid.

Even the researchers who created this image had a tough time interpreting its complex representation how of turbulent fluids flow in three dimensions.

4 For example, the Navier - Stokes equations are used all the time to approximate turbulent fluid flows around aircraft and in the bloodstream, but the math behind them still isn't understood.

Using further 3 - D dynamo simulations, which model the generation of magnetic field by turbulent fluid motions, Driscoll looked more carefully at the expected changes in the magnetic field over this period.

Instead, it is a dynamically active, essentially turbulent fluid, in which large - scale tracer patterns arise from active turbulence and do not necessarily imply domination of the physics and climate system by large - scale flow fields....»

Another technique, time microscopy, also exists, and was used by the laboratory Physique des lasers, atomes et molécules (CNRS / Université de Lille) to study instabilities similar to those observed in turbulent fluids.

Yet making progress is challenging, in part because their dynamics involve three - dimensional, turbulent fluid motions on the scale of a few meters, the nonlinear interaction of turbulence with the formation of cloud droplets, and the interaction of these cloud droplets with radiation (e.g. Wood (2012)-RRB-.

The average angle by which the players changed direction, like for particles in a turbulent fluid, was 120 degrees.

Wouter Bos at the École Centrale de Lyon in France and his colleagues have now tracked a turbulent fluid's motion by picking one point and following it as the fluid tosses it about.

The team directly measured terms in turbulence model equations, providing insights into the global nature of the mixing (e.g., faster mixing near the edges of the turbulent fluid layer when compared with the core) and identifying the dominant mechanisms governing the flow evolution.
