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. I am investigating DU-91-W2-250 and NACA 0018 airfoils. |
Projects:
