The course introduces students to the fundamentals of fluid mechanics as a basis for advanced courses in wind energy engineering. Topics include fluid properties, flow categories, streamlines, hydrostatics, transport equations (mass, momentum, energy), Bernoulli’s equation, boundary layer theory, and turbulence fundamentals. Students also study airfoil aerodynamics, similarity criteria (Strouhal, Froude, Euler, Reynolds numbers), and basic design of machines and mechanisms. An introduction to vibrations and vibroacoustics is included. The course combines theoretical lectures with exercises and laboratory classes to reinforce analytical and experimental skills.
