CFD simulations utilising the actuator disk model have been performed to study the effect of various parameters on the thrust produced by a tidal turbine. Instead of increasing the performance coefficients of the turbine, a turbine placed in blocked conditions is shown to experience a velocity higher than the inflow velocity using a new approach to interpret results from CFD simulations. Turbines...
The Blade Element Momentum (BEM) model is an important tool in initial turbine design and analysis, and its accuracy is dependent on various factors. Two factors were studied in this paper, and the results were compared across 2 scaled tidal turbines. Firstly, the effect of using multiple sets of lift and drag coefficients of the airfoil for different Reynolds numbers versus that of using a single...
