large-eddy simulation

large-eddy simulation

[¦lärj ¦ed·ē ‚sim·yə′lā·shən]
(fluid mechanics)
A technique for the prediction of complex turbulent flows in which the contribution of the large, energy-containing scales of motion is computed directly, and only the effect of the smallest scales of turbulence is modeled.

Long nonlinear internal waves, premelting dynamics, and large-eddy simulation of turbulent combustion are other areas explored.
The large-eddy simulation atmosphere and land surface model we developed is of considerable value for developing the concepts and techniques on how such parameterizations can be realized.
We show that Large-Eddy Simulation (LES) models that utilize modern, accelerated (e.g., by GPU or coprocessor), parallel hardware systems can now provide turbulence-resolving numerical weather forecasts over a region the size of the Netherlands at 100-m resolution.
