Comes after

  • Fluid mechanics 1

What it covers

Topics

  • Wind resource and statistics, Weibull distributions
  • Actuator-disc and one-dimensional momentum theory, the Betz limit
  • Blade-element theory
  • Blade-element momentum with tip, hub and Glauert corrections
  • Airfoil aerodynamics: lift and drag polars, angle of attack
  • Rotor design: chord and twist distribution, optimal power coefficient
  • Wakes and wind-farm interaction
  • Unsteady aerodynamics and dynamic stall
  • Loads and control: pitch, stall, tip-speed ratio

Results worth carrying out

  • Power coefficient, actuator disc

    cp=4a(1a)2,cp,max=1627 at a=13c_p = 4a(1-a)^2, \qquad c_{p,\max} = \tfrac{16}{27} \text{ at } a = \tfrac{1}{3}
  • Tip-speed ratio

    λ=ΩRU\lambda = \frac{\Omega R}{U_\infty}
  • Blade-element momentum, thrust on an annulus

    dT=4πrρU2a(1a)drdT = 4\pi r \rho U_\infty^2\, a(1-a)\, dr

Figures worth knowing

  • cp–λ curves
  • Actuator-disc streamtube
  • Airfoil polars
  • Induction-factor distributions

This map tells you what a course contains. The summaries, the tutoring and the people who already took it are the part you get by joining.

The topic outlines are not official syllabi. The university publishes a catalogue blurb per course, not lecture-by-lecture material, so each outline describes what a course of that name, at those hours, with those prerequisites teaches at engineering schools generally, cross-checked against the standard textbook for the subject. Treat it as an informed map, not as a transcript of the lectures.
