LES (Large Eddy Simulation)

Large Eddy Simulation (LES) is a computer modeling technique used to simulate turbulent flows, like wind around buildings or air through engines. It divides the flow into large, energy-carrying eddies (whirls) and smaller, more chaotic turbulent motions. LES explicitly calculates the large eddies, which have the most impact on flow behavior, while modeling the smaller ones. This approach provides a detailed and accurate representation of turbulence compared to simpler models, helping engineers and scientists better understand and predict complex fluid behaviors in various applications.
