摘要
双通道海流能发电设备可将海水的双向流动转化为叶轮的单向旋转。针对该通道结构，利用F1uent6．3软件MRF模型进行二维数值计算，分析叶片数目分别为4、6、8时，转动角度在5°-90°时，通道内流体的速度和压力分布，研究叶轮叶片数目和转动角度对通过发电设备的海水流量和设备的输出功率等性能参数的影响。计算结果表明，在一个性能参数变化周期内，随着叶轮转动角度的增加，通过设备的流量和发电设备的输出功率随之先增后减。随着叶轮叶片的数目增加，该设备的流量和发电设备的输出功率最大值峰值减小。
The author participates in the development the dual channel current power generation equipment, by which two-way current was transformed into single direction rotation of the impeller. Based on the channel structure, the Fluent 6.3 soft ware is complemented with MRF model by two-dimensional numerical calculating. Different rotation angels of 5-90 of 4 blades, 6 blades and 8 blades are studied by analyzing velocity and pressure contours inside the dual channel current power generation equipment. Also the effects of blade number and rotation angels on performance parameters of fluid flow and output power are studied for the dual channels equipment. The numerical results showed that during the parameters change cycle, the flow fluid and output power of the power generation equipment firstly increase and then decrease with the increase of rotation angles. In addition, the maximum flow fluid and the output power decrease with the increase of blade numbers.
