Cross Flow Turbine
Cross Flow Turbine
Water flows perpendicular to the device’s axis of rotation.
Cross flow turbines, also known as vertical-axis turbines, capture kinetic energy of moving water with spinning blades oriented perpendicular to the direction of flow. They can be mounted in either vertical or horizontal orientations. When mounted vertically, these devices can operate regardless of the direction of flow. They typically have cylindrical cross-sections amenable to placement in confined channels or allowing tight array spacing. Turbines can be open or ducted (shrouded) and placed anywhere in the water column, though bottom-mounted is the most common. The electricity production mechanism is similar to axial flow turbines.
