บทคัดย่อ

Renewable energy technologies are being developed to solve increasing electrical energy needs. Hydro energy is playing an important role. This paper presents a new concept of hydrokinetic turbine inspired by fish-like motion. The device is based on using an oscillating turbine to extract energy from vortices which are produced from an upstream cylinder. The objectives of this study were: 1) to find out the parameters which affected mechanical power and efficiency, 2) to find out the optimum condition of an oscillating water turbine and 3) to design a full-scale prototype with a cycle-averaged power of 100 W using the similarity methods. The results of the study were as follows: 1) mechanical power and efficiency depended on flow velocity U, diameter of cylinder D, longitudinal distance between cylinder and turbine S, friction torque T and spring stiffness k, 2) the optimum condition which defined as condition of an oscillating turbine with maximum efficiency was at Reynolds number Re = 50645, the ratio of the longitudinal distance between cylinder and turbine S to diameter of cylinder D = 10.4, the reduced friction torque T*= 2.7 , the reduced spring stiffness k*= 0.004 and 3) the dimensions of full-scale prototype with a cycle-averaged power of 100 W were presented. ฉ 2014 Published by Elsevier Ltd.
