v20 v21 3 3 One of the main challenges in LES modeling is the turbulence closure. The filtering process yields four SGS covariance terms (see the first five equations Sect. [wiki:doc/tec/gov governing equations]) that cannot be explicitly calculated. In PALM, three different subgrid-scale models are available to parameterize the SGS terms: 4 4 * [#deardorff_sgs Deardorff subgrid-scale model] 5 * [#d eardorff_sgs Deardorff subgrid-scale model (modified)]5 * [#dai_sgs Deardorff subgrid-scale model (modified)] 6 6 * [#dynamic_sgs Dynamic subgrid-scale model] 7 7
