Abstract

A straight-bladed vertical-axis turbine for wave energy conversion has been proposed in order to develop a novel air turbine suitable for oscillating water column based on wave energy plant. The objective of this study is to show the effect of guide-vane geometry on the performance of straight-bladed vertical-axis turbine. The experimental study was carried out by a wind tunnel. The rotor has four straight blades with a profile of NACA0018, a chord length of 80.5 mm, a pitch diameter of 460 mm and a blade width of 490 mm. In this study, the performances of three types of guide-vanes (i.e. an arc, a semi-arc, and a semi-arc having a straight part) were compared by experiments.
