Question

An experimental ocean current turbine (OCT) is deployed in the Gulf Stream off the

coast of Florida. The OCT is at a depth of 50m where the Gulf Stream current velocity is

1.5 m/s. The turbine is located in an area where ocean depth is 100m and waves of H =

2m height are propagating with T = 12s. There is also a wind driven current uw that

needs to be considered. Take uw(0) = 0.3 m/s. If the turbine has a rotor diameter of 4m,

calculate the power generated by the turbine using momentum theory. Take axial

induction factor a =

1/3 and ρ = 1025 kg/m3. Assume that ocean current, wave, and wind driven current are

in the same direction.
