摘　　要：针对研发出的可将海水的双向流动转化为叶轮的单向旋转的双通道海流能发电设备,利用Fluent 6.3软件MRF模型进行了二维数值计算,分析了叶轮转速为0.3 rad/s时,转动角度在5°-90°时,通道内流体的速度和压力分布,研究了弧形叶片和平叶片在不同的转动角度下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。The dual channel current power generation equipment is developed, in which, two-way current is transformed into single direction rotation of impeller. Based on channel structure, the FLUENT 6.3 soft ware complemented with MRF model is used to carry out two-dimensional numerical calculation. The flow velocity and pressure distributions inside dual channel current power generation equipment are analyzed by the model under the conditions of rotation angels of 5°-90° and impeller rotating speed of 0. 3 rad/s. The effects of curved blade and straight blade on the performance parameters of flow and output power are also studied under the condition of different rotating angles.
