Celebrating Research Excellence in Wind Energy and Atmospheric Flow ModelingLausanne, 25 June 2026 – The EPFL WiRE lab proudly congratulates Dr. Marwa Souaiby on the occasion of her public PhD defense ceremony, during which she presented her doctoral thesis, “Interactions of Wind Farm Wakes with the Atmospheric Boundary Layer under Varying Stability Conditions: Numerical and Analytical Studies.”Dr. Souaiby’s research addresses fundamental challenges in understanding and predicting wind-farm flows under realistic atmospheric conditions. As wind farms continue to expand in size and density, accurately modeling the evolution of turbine wakes becomes increasingly important for maximizing energy production and improving wind-farm design.Combining high-fidelity large-eddy simulations (LES) with physics-based analytical models, her work provides new insights into the interactions between wind-farm wakes, atmospheric turbulence, and stability conditions. The thesis introduces improved analytical approaches for predicting wake recovery and power production while preserving the computational efficiency required for practical engineering applications.A significant contribution of the research is the validation and enhancement of wake models across stable, neutral, and convective atmospheric boundary layers. The study also explores how atmospheric stratification, gravity waves, and interactions between neighboring wind farms influence wake development and overall farm performance.Through these advances, Dr. Souaiby’s work contributes to a deeper understanding of wind-energy systems and offers improved predictive tools for the planning, operation, and optimization of future wind farms and wind-farm clusters.The WiRE team community extends its warmest congratulations to Dr. Marwa Souaiby and celebrates this important milestone in her academic and professional journey. We wish her continued success in her future research and career endeavors.© 2026 EPFL
