采用CFD技术对不同通道形式平板型建筑的风能利用进行了数值研究,分别模拟了具有等截面通道和四个不等截面通道(渐缩型通道、渐扩型通道、渐缩—渐扩型通道和流线型通道)的五种平板型建筑周围的风场,以风能和风能密度为基础,提出了评价平板型建筑物集风效果的三个系数,得到了平板型建筑集风效果最优的通道形式及最佳A值,为进一步探讨建筑环境中充分利用风能打下了基础。
The CFD technology was used to study the wind energy utilization of flat-type buildings with different passageways. The flow field with equal cross-section and four unequal cross-sections (tapering, diverging, tapering-diverging And the streamlined channel) five winds around the flat-panel buildings, based on the wind energy and wind energy density, put forward three coefficients to evaluate the wind-collecting effect of the flat-type buildings, Form and the best value of A, laying the foundation for further exploration of the full use of wind energy in the building environment.
