Large Eddy Simulation (LES)

Large Eddy Simulation (LES) is a computational technique used to model turbulent fluid flows by directly calculating the larger, energy-carrying swirling motions (eddies), while approximating smaller, more chaotic motions. It strikes a balance between detailed accuracy and computational practicality, making it useful for studying complex flows such as air around aircraft or water in turbines. By focusing on the dominant large structures, LES provides insights into flow behavior and turbulence effects that are more precise than traditional methods, aiding in design, analysis, and optimization across engineering and scientific applications.
