Impact of Channel Blockage on the Performance of Axial and Cross-Flow Hydrokinetic Turbines

This work investigates the effect of channel blockage on how axial and cross-flow turbines perform. The objective is to fill a gap in the literature on suitable blockage corrections for cross-flow turbines. The investigation is based on 3D computational fluid dynamics simulations at a high Reynolds number. Blockage corrections are proposed for axial and cross-flow hydrokinetic turbines.
