Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading
Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance
