Question

2. Regarding the derivation of the ideal HAWT with wake rotation using momentum theory

a. What is the definition of the angular induction factor?

b. Show the two key equations that are equated in derivation of Cp when including wake

rotation.

c. Use the equation derived for Cp,max (Manwell Eqn 3.40) and calculate the Cp,max for a

blade operating at a tip speed ratio of 4.0. Show the calculation methodology.
