【摘要】 以浓缩风能型风力发电浓缩装置为研究对象,进行了CFD计算和实验验证,结果表明仿真与实验很好的吻合。仿真与实验结果是浓缩装置内流速与来流的风速增加等级基本相近;浓缩装置内的流场以中心轴为轴对称的环形分布流场;工作段(中央圆筒)处呈现以轴为圆心随半径加大风速逐渐增加,近壁面形成一层薄薄的边界层,边界层内速度急剧下降,直到壁面的速度为零。更多还原

【Abstract】 The Article concentrated the concentration device of concentrated Wind Energy Turbines as the object of study and undertook the CFD calculations and experimental verification.The results show that good agreement of simulation and experiment.Simulation and experimental results is basic similar in the increased level of flow rate and wind speed in the concentration device.The flow field in the concentration device is a central axis symmetric annular distribution.Meanwhile,With the axis as the center of a circle with the radius increase,wind speed is gradually increased.The working segment(central cylinder),Near wall formed a thin boundary layer.There is a sharp decline in velocity in boundary layer until the wall surface of zero velocity.更多还原
