摘要

涡轮机是将流体运动转换为旋转运动的机械装置。在这项研究中，水波被用作流体。使用Ansys Fluent的流体体积（VOF）模型，获得规则波来分析波浪箱中涡轮机的运动。涡轮机的力、压力、力矩和速度对于从波浪能中获得电能是重要的。因此，在本研究中，研究了这些参数随波浪影响的变化。观察到这些参数值随着波浪高度的增加而增加。观察到涡轮的动压和动力矩随着波长的增加而增加。然而，涡轮机的转速随着波长的增加而降低。作用在叶片上的力并没有随着波长的增加而改变，只是造成了时间的延迟。然而，观察到，对具有2m的波浪高度的涡轮机叶片施加了非常高的力，并且该值达到8000N。此外，在2m的波长和20m的波长下获得了最大涡轮机速度，达到87mm/s。

Turbine Type Rotary Wave Energy Converter Performance

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.
