| 116 | The example run for using the wind turbine model in PALM is called "wind_turbine_model" and can be found at [https://palm.muk.uni-hannover.de/trac/browser/palm/trunk/TESTS/cases/wind_turbine_model/ trunk/TESTS/cases/wind_turbine_model]. This example shows the application of an enhanced actuator disc wind turbine model (Actuator Disc Model with Rotation, ADM-R) in PALM. The model is based on blade elements and conversion of airfoil lift and drag coefficients from the NREL 5MW reference turbine (see above) to local forces on the flow. The example simulates 4 different turbines in a turbulent shear flow. After 30s of simulated time, the turbines start to correct their orientation by use of a yaw controller. |

| 118 | For the input, you need the common steering file (wind_turbine_model_p3d), which defines, among other things, cyclic lateral boundary conditions and constant potential temperature (300K) and constant geostrophic wind (ug = 6 m/s) profiles for initialization. To run the wind turbine model successfully, a second file is needed. It's called _wtm (wind_turbine_model_wtm. It consists of important properties of the NREL 5MW model turbine and will be automatically read by PALM |

| 120 | To start the model, no further modifications are necessary if you use one of the default .palm.config-files in trunk/SCRIPTS/. The palmrun call reads: |
| 121 | palmrun -r wind_turbine_model -a "d3#" -c imuk_default -T 4 -X 4 |
| 122 | |
| 123 | The monitoring files you get after the run (wind_turbine_model_rc and wind_turbine_model_wtm_T01-T04) should be similar to the attached files. No postprocessing of the data is required. |
