大气边界层湍流特性的风洞模拟实验研究
Wind tunnel experimental simulation of turbulent characteristics of atmospheric boundary layer
摘要
Abstract
Barriers were added to the original combination of spires and cubes to enhance the accuracy of experimental simulation for the atmospheric boundary layer (ABL) turbulent characteristics. 8 different configurations were tested in this experiment by adjusting the turbulence devices' position, and the influence mechanism of spires, cubes, and barriers on the boundary layer was analyzed respectively. The terrain type was obtained by comparing the wind velocity profile index between the simulated results and the corresponding standards. Then, the simulated terrain type was further verified by taking the geometric similarity into account and contrasting with international standard ASCE7. The results show that downstream -barriers can significantly increase the turbulence intensity and improve the integral length scale in the lower part of the boundary layer;the combination of spires, downstream-cubes and downstream-barriers can well achieve the simulation of terrain B under the scale factor 1∶267 in the wind tunnel.关键词
