Blades' flow field simulation of a vane current generation device

摘要:

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.

Abstract:

To understand blades' impact on the flow field distribution of the new vane current generation device based on the device model of Shanghai Ocean University, FLUENT software was used to numerically simulate the flow field. Moreover, the velocity and pressure contours of different blade shapes were obtained.Through the comparison of different blade shapes' velocity and pressure distribution,we found different blade shapes can play a certain role in changing and developing the exterior flow field and operating the vane current generation device smoothly. The flow field analysis results fully confirmed that the reasonable design of the blade shapes can play an important role in force tolerance of the generation device and improving the flow distribution, and also provided reliable theoretical reference for the optimization of the device.
