Dynamic behavior of novel vertical axis tidal current turbine: Numerical and experimental

A discussion on the design, construction, and test of a novel patented vertical axis and variable pitching blade hydro turbine, named KOBOLD, capable of harnessing clean and renewable energy from marine tidal currents, presented at the 15th International Offshore and Polar Engineering Conference (Seoul, Korea 6/19/2005), covers theoretical analysis and numerical prediction performances, which have been compared and validated with experimental test results on both model and real scale turbines; recent activities in terms of numerical and experimental investigations on vertical axis hydro turbines; and flow curvature effects
