A Hydrodynamic Productivity Of Maritime Current Turbines Is Predicted. It is described how a blade element momentum (BEM) model was developed for the hydrodynamic design of maritime current turbines. Interpolation of 2D section data and extrapolation for stall delay are included in the model. The numerical model is compared to experimental data acquired from cavitations tunnel testing of an 800 mm diameter model rotor. Theoretical predictions match the results of the experiments very well. A typical 3D rotor is utilized to illustrate parametric changes of the design parameters using this verified model. For this rotor, the impact of tip immersion on potential cavitations is evaluated. The model is then utilized to solve the tidal profile's dynamic impacts. The impact of increasing blade roughness is shown, with a very modest decrease in power. This research shows that the created numerical model may be used to investigate the hydrodynamic design and operate of maritime current turbines.
