Wave energy converter of oscillating water column has simple structure and
small flexibility. The partial loss of incident energy reflected back by oscillating
water column is related to the front wall and air compressibility. Wave energy
converters of oscillating water column are usually located at high-energy density
points in the ocean. As shown in Fig. 14.3, the parabolic wall extending in front of
the oscillating water column wave energy converter collects wave energy, which
can receive more incident wave energy.
