为了解叶片形状对叶片式海流能发电装置流场分布的影响,以上海海洋大学研制的叶片式海流能发电装置为原型,采用FLUENT软件对7种不同形状的叶片进行了流场数值模拟,获得了不同形状叶片的速度云图及压力云图。通过比较分析不同形状叶片的外流场速度分布和压力分布情况可知,不同叶片形状对叶片式海流能发电装置外流场变化发展以及稳定运行具有一定作用。该流场分析结果充分证实了叶片形状的合理设计对实现海流能发电装置的受力情况和改善流场分布具有重要作用,并为后期装置的优化提供了可靠的理论参考依据。
In order to understand the influence of blade shape on the flow field distribution of blade-type sea current energy generation device, a leaf-type current-flow power generation device developed by Shanghai Ocean University was used as a prototype. Flow field numerical simulation was performed on seven different shapes of blades using FLUENT software, The speed of different shapes of leaf cloud and pressure cloud map. By comparing the velocity distribution and pressure distribution of outflow field in different shape blades, we can see that different blade shapes play a certain role in the development and stable operation of the flow field in the blade-type current-generating unit. The results of flow field analysis fully confirm that the rational design of the blade shape plays an important role in the realization of the force distribution and the distribution of the flow field of the sea current energy generation device, and provides a reliable theoretical reference for the optimization of the subsequent device.
