Tidal Energy Round Robin Tests: A Comparison of Flow Measurements and Turbine Loading

A Round Robin Tests program is being undertaken within the EC MaRINET2 initiative. This programme studies used facility influence can have on performance evaluation of a horizontal axis tidal turbine prototype when it operated under wave and current conditions. In this paper, we present design experiments that throughout work results related to flow characterisation obtained at Ifremer circulating tank, Cnr-Inm towing tank ocean research FloWave. These facilities been identified provide adequate geometric conditions accommodate 0.724 m diameter operating velocities 0.8 1.0 m/s. The set-up replicated in each with exemption amount measuring instruments. Intrinsic differences creating currents between are found. Flow up 10% higher than nominal values amplitudes target by factor 2. discrepancies generation methods facility. When velocity measured besides rotor, presents an increase 8% compared upstream measurements.
