Large Eddy Simulation (LES) is a computational fluid dynamics technique used to model turbulent flows. It focuses on resolving the large-scale structures of turbulence while modeling the smaller, less significant scales. This approach allows for a more accurate representation of complex flow phenomena, making it useful in various engineering applications. LES is particularly beneficial in fields such as aerospace engineering, climate modeling, and automotive design. By capturing the essential dynamics of turbulence, LES provides insights into flow behavior that can improve performance and efficiency in systems where fluid motion plays a critical role.
