摘要
扩散体建筑是用来汇集风能的建筑形式。通过风洞试验,研究了3种具有不同截面形状的扩散体建筑对增强风速及强化风能的效果。试验结果表明:截面形状为肾形的建筑其风力集结效果最好,可利用风能的高度范围较大;截面形状为椭圆形和扩压风道形的建筑也具有良好的效果。通过对试验数据与模拟数据比较分析可见,风洞试验得到的数据与模拟结果较为吻合,既验证了数值模拟结果的准确性,又为建筑环境中风能利用的研究奠定了试验基础。
The diffuser building is a kind of architecture pattern for concentrating wind energy. Three different diffuser buildings＇ effects on intensifying wind speed and wind energy are studied in the wind tunnel The results show that the effect of concentrating wind energy is the best for the buildings whose section is of kidney form, and the available height range of wind energy is large; the effect is also fine for the buildings whose sections are of ellipse form and of pressure diffusion duct. By comparing and analyzing the experimental data and the results of numerical simulation, we draw the conclusion that the experimental data is identical with the results of simulation, it not only validates the accuracy of the numerical simulation, but also lays experimental foundation for the study on wind energy utilization in the built environment.
