Abstract
This study aimed to develop horizontal spiral turbines for generating electricity by designing spiral turbines using the Golden Ratio function. The study analyzed the impact of the diameter-length ratio and the number of the turbine's blades (2 - 6 blades) on the torque of turbine. Then the prototype of the spiral turbine with a 0.6 meter diameter and 0.9 meter blade was designed to generate electricity with a water velocity of 1, 1.5 and 2 m/s in order to compare to the propeller turbine which had an identical diameter size. The results indicated that a 3-bladed spiral turbine with a 2/3 of diameter-length ratio of turbine had maximum torque at 1 m/s of water velocity. The spiral turbine produced an optimal efficiency of 48% which was 15% higher than that of the propeller turbine.
