WIND TURBINE GEOMETRY

- DTU10MW Model-Scale, from the UNAFLOW project experimental campaign in Politecnico di Milano's wind tunnel.

- As described in "UNAFLOW: a holistic wind tunnel experiment about the aerodynamic response of floating wind turbines under imposed surge motion", DOI: 10.5194/wes-6-1169-2021

SIMULATIONS DESCRIPTION

- CFD solver ReFRESCO 2023.1.0

- Unstructured hexahedral meshes generated using Hexpress:    - G1 - 16.7M cells    - G2 - 21.9M cells    - G3 - 59.5M cells

- Turbulence models tested:    - RANS - k-omega SST 2003    - DDES - k-omega SST 2003    - PANS - k-omega SST 2003 (fk tested of 25%, 50% and 75%)

- Inputs:    - controls.xml (ReFRESCO input parameters)

- Outputs:    - Residuals    - Courant number    - Forces on surfaces of the turbine    - Moments on surfaces of the turbine    - y+    - Linear solver iterations    - Velocity monitors in the wake (replicating UNAFLOWs hot-wires)    - Volumetric flow data in CGNS format (only for RANS case with grid G2 due to space limitations of the repository)

    Note: _unstd monitors include information for each non-linear iteration.
