为了研究风力机在二维山脊的排布,采用CFD商用软件对二维山脊进行了数值模拟,发现压缩效应的存在使来流风速在山脊顶端速度增大,而山脊下游流动紊乱,不适合放置风力机。在二维山脊顶端放置一台风力机,对山脊和风力机进行数值模拟显示,压缩效应的存在使山脊顶端风力机所受扭矩增大。在二维山脊顶端放置一台风力机,同时按照文章得出的最佳距离在其上游放置一台风力机进行数值模拟,分析了上游风力机对二维山脊和山脊顶端风力机的影响。
In order to study the influence of 2D-ridge on the wind turbine arrangement,firstly a2D-ridge was numerically simulated by using the commercial CFD software in this paper, the compression effect was found in the field, and the downstream of 2D-ridge was so turbulent that it was not suitable for the wind turbine to work there. And then a working condition in which a wind turbine was placed on the top of the 2D-ridge was simulated, the result shown that torque of wind turbine increased because of compression effect. The placement of a wind turbine in the upstream of 2D-ridge was simulated to find the best distance between the wind turbine and the 2D-ridge.Finally a wind turbine was placed in the upstream of the 2D-ridge according to the optimal distance gotten from this paper, and another wind turbine was placed on the top of the 2D-ridge, a simulation was carried out to study the influence of upstream wind turbine on the 2D-ridge and the wind turbine on the top of 2D-ridge.
