Synthetic Turbulence Generator Parameters

Since revision r2259, a synthetic turbulence generation method is available in PALM. The turbulence generator follows the method proposed by Xie and Castro (2008) with a modification by Kim et al. (2013).

All parts of the synthetic turbulence generator are modularized in module synthetic_turbulence_generator_mod. In this context, a new Fortran NAMELIST stg_par was added, containing all related steering parameters.


NAMELIST group name: stg_par

Parameter Name FORTRAN Type Default Value Explanation

use_syn_turb_gen

L

.F.

Flag to switch on the synthetic turbulence generator. If use_syn_turb_gen = .T., it is required to also set initializing_actions to either 'set_constant_profiles' or 'read_restart_data'. Also, non-cyclic boundary conditions along x-direction (bc_lr='dirichlet/radiation') and cyclic boundary conditions along y-direction (bc_ns='cyclic') have to be used.

Using turbulence recycling (turbulent_inflow=.T.) together with the synthetic turbulence generator is not allowed.
