Abstract—Hydro kinetic water wheel turbines are known to be conventional systems for energy harvesting in rural communities around the globe. Different turbine systems have been analyzed to produce promising energy with a head difference ranging from 1-100’s of meters but little has been done to come up with a zero head system for energy harvest mainly due to the fact that their efficiencies have not being studied well and optimized. The concept of this research concentrates on the angle of inclination of this turbine with respect to the water flow in an undershoot zero head system. In this research, series of experiments were conducted on 3 different turbines with equal width and diameter of 220(mm) each. Angle of inclination of this turbines varies in to 30o, 60o and 90o with respect to the water flow. Performance of these turbines is studied and the output power, torque, and efficiencies are compared to ascertain the best in such condition. Each turbine was designed using a plastic plate of 2(mm) thickness. Potential of this type of turbine is displayed to be used in a zero head flow to harness the loss energy of free flowing waters in irrigation canals and water streams.
