Turbulence Closure
Page is under construction!
PALM offers different turbulence closures depending on the scope of the simulation.
LES
Per default, PALM is operated as an LES model using a subgrid-scale model to parameterize turbulence of size smaller than the grid size. This is descibed in more detail here.
RANS
Switching on the RANS mode via the namelist paramter rans_mode, PALM is operated as a RANS model. Now, all turbulence is parameterized using a turbulence model. The available turbulence parameterizations are described here.
