【摘要】：针对研制的一种双通道海流能发电设备,利用Fluent 6.3软件结合MRF模型进行了二维数值计算,分析了叶轮转速在0.1~1 rad/s,转动角度在10°~90°时,通道内流体的速度和压力分布,研究了叶轮转速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,当叶轮转动角度为30°~50°时,在相同的叶轮转动角度情况下,叶轮转速较小时,流量较大;当叶轮转动角度大于60°时,在相同的叶轮转动角度情况下,随着叶轮转速的增加,通过发电设备的流量和发电设备的输出功率逐渐增加。
[Abstract]:In this paper, a two-channel ocean current power generating equipment is developed. The 2-D numerical calculation is carried out by using Fluent 6.3 software and MRF model, and the impeller rotational speed is analyzed at 0.1 rad/s. When the rotation angle is 10 掳~ 90 掳, the velocity and pressure distribution of the fluid in the channel are obtained. The influence of impeller speed on the performance parameters such as seawater flow rate and output power of the equipment through power generation equipment is studied. The results show that in a period of variation of performance parameters. When the rotation angle of the impeller is 30 掳/ 50 掳, under the same rotating angle of impeller, the speed of the impeller is small and the flow rate is larger. When the rotation angle of the impeller is greater than 60 掳, with the increase of the speed of the impeller, the flow rate of the generating equipment and the output power of the generating equipment increase gradually under the same rotation angle of the impeller.

【正文快照】： 近年来国内外对海流能的研究较活跃,文献[1-3]研究了稳定海流方向的垂直轴流式海流发电装置及其性能,发电装置安装在海底,对海流能的利用局限在海底区域,而不能应用于近海区域的往复海流;文献[4-7]研究了水平轴流式海流能发电装置及性能,可适用于双向的潮流流动,但需要较复杂
