文摘
- •
The dynamic model of the U-OWC wave energy harvester is revisited.
- •
It is based on the use of unsteady Bernoulli equation with experimental head losses.
- •
Field data show that the current model overestimates the system response.
- •
A more refined response is obtained by including unsteady head losses.
