Abstract
A systematic understanding regarding the interaction between the atmospheric boundary layer, the wind turbines and their wakes is highly important in current wind energy research. Because a deep insight of the aerodynamic behavior in wind farm can help to determine a feasible wind farm control strategy to optimize the global power capture and minimize the blade loadings. To this end, a high-fidelity CFD tool is employed in this project to simulate turbine-turbine interactions inside a scale wind farm facility. This scaled wind farm is located in a boundary layer wind tunnel, which is able to provide for high quality atmospheric boundary layer. The CFD tool is developed based on a standard incompressible solver in finite volume repository. Large-eddy simulation is employed for turbulence modeling. Both the conformed body mesh and direct forcing immersed boundary method are used to model geometries such as turbulence generator, scaled wind turbine, etc. The whole system operates at high Reynolds number, which normally requires significant computation resources to properly resolve the freestream and surface boundary layer.
