Experiments on the hydrodynamic performance of horizontal axis marine current turbines to confirm computational predictions

Converting the kinetic energy provided by ocean or marine currents is an intriguing prospect since it may provide a consistent and predictable energy source. The bulk of the suggested designs for converting this kind of kinetic energy are based on the horizontal axis turbine idea, which has many of the same features as wind turbines. Although wind turbine technology may teach and transmit a lot, there are some major distinctions. The consequences of the free surface and the development of cavitations are among them. As a result, any numerical techniques created must be validated. This paper describes the creation and testing of two simulation tools based on blade element momentum theory: a commercial code (GH-Tidal Bladed) and an inhouse academic code (SERG-Tidal). Experimental data in a cavitations tunnel and a towing tank were used to validate a model 800 mm diameter turbine. Measurements of shaft power and thrust produced by the turbine for a variety of blade pitch settings and speeds are included in the experimental data. The outcomes of the two codes are compared and contrasted. These findings suggest that the two created codes provide comparable results and offer a good approximation of experimental turbine performance. These findings provide the required trust in the generated codes, resulting in suitable tools that may be used by marine current turbine producers.
