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.
