Vortex-type"s micro-hydro water turbine is a new technology for harvesting energy from water which the performance is still providing more challenge. After having designed the vortex-type water turbine in previous work, a laboratory-scale experimental apparatus is built to prove the design and to validate numerical simulations of the turbine The important design parameters such as torque, power, and efficiency are considered. It is found that the CFD results gives higher torque, power, and efficiency compared to experiments results with a similar trend. This is due to no feature in the used CFD software in evaluating mechanical friction that happened in experiments device, for more specific in torque-meter used. Head of CFD for discharge of 2.7 L/s and 2.8 L/s are 0.06 m and 0.06 m while from experiment is 0.07 m and 0.072 respectively. ANSYS has been used for CFD simulation.
