INTRODUCTION Cross-flow turbines present several advantages over axial flow types for power generation from moving water. First, the rectangular form factor is well suited to take advantage of the hy-drokinetic energy often concentrated in shallow channels. This form factor presents an opportunity to construct arrays with high blockage (ratio of swept area(More)
—The energy conversion efficiency of a straight-bladed cross-flow turbine is examined experimentally. The preset pitch angle of the turbine blades is shown to have a large impact on turbine performance for two and four-bladed turbines over the range of tip-speed ratios tested. The optimal preset pitch angle was found to be 6 • for both turbines and nearly(More)
