I am a Ph.D. Student and Teacher at Warsaw University of Technology. My research topics are the aerodynamics of wind energy turbines and Computational Fluid Dynamics. I am a massive fan of Vertical-Axis Wind Turbines, including Savonius- and Darrieus-type turbines. I am working on modeling laminar-to-turbulent transition in boundary layers. 

Projects:

„Analiza numeryczna przejścia laminarno-turbulentnego na łopatach pracującej siłowni wiatrowej Darrieusa” (Numerical analysis of laminar-to-turbulent transition on Darrieus wind turbine blades) – Interdisciplinary Centre for Mathematical and Computational Modelling University of Warsaw – grant HPC GB83-33

„Wpływ warstwy przyściennej łopat siłowni wiatrowej o pionowej osi obrotu na konwersję energii wiatru.” (Effect of boundary-layer of vertical-axis wind turbine blades on wind energy conversion.) - ENERGYTECH-3: Impulse – Faculty of Power and Aeronautical Engineering, 2021-2023
