Abstract
Turbines are mechanical devices that convert fluid motion into rotational motion. In this study, water wave is used as fluid. Ansys Fluent's Volume Of Fluid (VOF) model is used and regular waves are obtained to analyze the movement of the turbine in the wave tank. The force, pressure, moment and speed of the turbine are important to obtain electrical energy from wave energy. For this reason, in this study, the change of these parameters with the effect of the wave is examined. It is observed that these parameter values increased with increasing wave height. It is observed that the dynamic pressure and moment of the turbine rise with the increase of the wavelength. However, the speed of rotation of the turbine decreased with the increase of the wavelength. The force coming to the blades did not change with the increase of the wavelength, it only caused a delay in time. However, it was observed that a very high force was applied to the turbine blades with a wave height of 2 m and this value reached 8000 N. In addition, the maximum turbine speed was obtained at a wavelength of 2 m and a wavelength of 20 m, reaching 87 mm / s.
期刊介绍：
The scope of the “Gazi University Journal of Science” comprises such as original research on all aspects of basic science, engineering and technology. Original research results, scientific reviews and short communication notes in various fields of science and technology are considered for publication. The publication language of the journal is English. Manuscripts previously published in another journal are not accepted. Manuscripts with a suitable balance of practice and theory are preferred. A review article is expected to give in-depth information and satisfying evaluation of a specific scientific or technologic subject, supported with an extensive list of sources. Short communication notes prepared by researchers who would like to share the first outcomes of their on-going, original research work are welcome.
