Numerical analysis on a self-rectifying impulse turbine with U-shaped duct for oscillating water column wave energy conversion
TLDR
In this paper , a self-rectifying impulse turbine with U-shaped duct is proposed for oscillating water column wave energy conversion, which has a pair of fixed, symmetrical and radial-flow guide vane rows, and an axisymmetric, U-shape duct with increasing cross-sectional area from the rotor to the guide vanes, therefore it is expected to be relatively simple, reliable and efficient.About:

TL;DR: In this paper, a new topology that uses twin unidirectional turbines (which feature a high efficiency spanning a broad range) is proposed, and it is shown that the power output from such a module considerably exceeds existing optimal configurations including those based on a fixed guide vane impulse turbine or a Well's turbine.

Scaling and air compressibility effects on a three-dimensional offshore stationary OWC wave energy converter
TL;DR: In this article, scaling and air compressibility effects on the performance of an offshore stationary OWC wave energy converter are studied in a 3D numerical wave tank, where a Computational Fluid Dynamics (CFD) model based on the RANS equations and the VOF surface capturing scheme is developed and validated against physical measurements of a 1:50 model-scale OWC.
