WebLarge Eddy Simulation (LES) Large Eddy Simulation ( LES) is one of the most promising methods for computing industry-relevant turbulent flows. It is used to predict unsteady flow behaviors with lower computational cost as compared to Direct Numerical Simulation (DNS). The essential idea of LES dates back to Joseph Smagorinsky (1963) in ...
