Short summary
Short summary
The energy yield of wind turbines within wind farms can be increased with control strategies. One way consists in misaligning the turbines with respect to the wind direction, to redirect their wake away from downstream turbines. Using models and advanced simulations, this work confirms a true potential but stresses how measurement biases on the wind direction and the flow complexity may critically affect both the performance in the field, and the reliability of the field validation campaigns.

Short summary
This article presents an advanced tool designed for the high-fidelity and high-performance simulation of operating wind turbines, allowing for instance the computation of a blade deformation, as well as of the surrounding airflow. As this tool relies on coupling two existing codes, the coupling strategy is first described in depth. The article then compares the code results to field data for validation.

Short summary
To increase power production, wind turbines' size continues to grow, reaching larger-scale processes. A better comprehension of the involved physics is required. This study focuses on the simulation of stable boundary layers using unstructured grids. This original framework is validated on a neutral boundary layer scenario, followed by a stable boundary layer scenario. All results are within the range of initial benchmarks. The framework is validated.
