| 1703 | Turbulent inflow is realized using the turbulence recycling method from Lund et al. (1998, J. Comp. Phys., 140, 233-258) modified by Kataoka and Mizuno (2002, Wind and Structures, 5, 379-392). |
| 1704 | |
| 1705 | A turbulent inflow requires Dirichlet conditions at the respective inflow boundary. So far, a turbulent inflow is realized from the left (west) side only, i.e. bc_lr = 'dirichlet/radiation' is required! |
| 1706 | |
| 1707 | The initial (quasi-stationary) turbulence field should be generated by a precursor run and used by setting initializing_actions = 'cyclic_fill'. |
| 1708 | |
| 1709 | The distance of the recycling plane from the inflow boundary can be set with parameter recycling_width. The heigth above ground above which the turbulence signal is not used for recycling and the width of the layer within the magnitude of the turbulence signal is damped from 100% to 0% can be set with parameters inflow_damping_height and inflow_damping_width. |
| 1710 | |
| 1711 | The detailed setup for a turbulent inflow is described in chapter 3.9. |
