Abstract
A Vertical-Axis Hydrokinetic Turbine (VAHT) with an augmented channel was designed, fabricated, and tested by characterizing its mechanical power output and coefficient of power in terms of three parameters: inlet reference angle and outlet angle of the channel vanes, and turbine propeller height. A flume channel set-up was used as a test rig with mechanical power output and coefficient of power as response variables. Analysis revealed that mechanical power output and coefficient of power as response variables. Analysis revealed that mechanical power and coefficient of power were significantly affected by all three independent factors. The study determined that the highest coefficient of power of 48% occurred at 45° inlet reference angle, 15° outlet angle, and 7cm turbine height. Similitude modeling using the Froude number was used on this combination and the relationship between the flow velocity and turbine diameter power output and flow velocity and power output turbine diameter of the prototype turbine were presented.
