A Comparison of Tidal Turbine Characteristics Obtained from Field and Laboratory Testing

Experimental testing of physical turbines, often at a smaller scale, is an essential tool for engineers to investigate fundamental design parameters such as power output and efficiency. Despite issues with scaling blockage which are caused by limitations in size flow velocity the test facilities, experimental tank laboratory environments perceived offering more control thus trustworthier results than field testing. This paper presents tests tidal turbine, performed using self-propelled barge real still water conditions, that compared towing test. Factors influencing performance characteristics, choice sensor, vessel handling data processing techniques investigated this paper. Direct comparison exact same turbine obtained facility further confirms robust analysis capabilities viable, time cost efficient alternative characterise turbines.
