Webb28 juli 2009 · Abstract. Restrictions on computing power make direct numerical simulation too expensive for complex flows; thus, the development of accurate 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.
