Abstract
This paper presents a comparison of 0.6m Impulse and Wells turbines with same hub to tip ratio of 0.6 for wave energy power conversion under similar conditions. A 0.6m Wells turbine rotor with a solidity of 0.6, with guide vanes, was tested in a 0.6m test rig. Similarly, an Impulse turbine rotor consisting of 30 blades and with a set of symmetrical guide vanes on both upstream and down stream sections was tested under similar flow as well as testing conditions. This paper reports the comparison of performance characteristics of both these turbines under similar uni-directional steady flow conditions. Based on this uni-directional steady investigation, it was seen that the Wells turbine might suit small wave sites whereas the impulse one might be ideal for large wave sites. This observation needs further investigation and authors are working on enhancing this comparison under irregular, unsteady real sea conditions.
