WebbModeling turbulent flows often involves applying a model that reduces the complexity of turbulence and simplifies computation. One of these models is the large eddy … Large eddy simulation (LES) is a mathematical model for turbulence used in computational fluid dynamics. It was initially proposed in 1963 by Joseph Smagorinsky to simulate atmospheric air currents, and first explored by Deardorff (1970). LES is currently applied in a wide variety of engineering … Visa mer The governing equations of LES are obtained by filtering the partial differential equations governing the flow field $${\displaystyle \rho {\boldsymbol {u}}({\boldsymbol {x}},t)}$$. There are differences between … Visa mer Large eddy simulation involves the solution to the discrete filtered governing equations using computational fluid dynamics. LES resolves scales from the domain size Visa mer To discuss the modeling of unresolved scales, first the unresolved scales must be classified. They fall into two groups: resolved sub-filter … Visa mer • Heus, T.; van Heerwaarden, C. C.;Jonker, H. J.
