摘要:

为获得单山和双山情况下三维山体的风场特性,研制风洞中用于同步测试多点风速的试验装置和支撑构架,进行不同坡度下单个山体风场的测试,进行2个山体在前后和左右排列情况的测试,并分析山体距离和坡度的影响.研究表明:单山情况下山体横风切面的加速效应大于顺风切面,横风切面3/4山体高度至山顶为风速增大的最不利位置.在前后紧密排列情况下,前山的风速与单山情况比较接近,后山的风速小于单山情况.在左右排列情况下,山顶的加速效应略大于单山情况,峡谷侧山体的加速比大于单山情况.

Abstract:

A set of experimental equipment and supporting frame were developed, which can measure the wind velocities of multiple points simultaneously in a wind tunnel,in order to study the wind field characteristics on threedimensional hills under isolated hill and two adjacent hills condition, The wind velocities on isolated hills with different slopes were tested. The wind velocities on two adjacent hills with frontrear and leftright arrangement were also tested and the influence of hill distance and slope to the velocities were investigated. Results show that, for the isolated hill condition, the speedup effects on the crosswind plane are more significant than those on the alongwind plane, and the most unfavorable position are ranged from threequarter hill height to the top of the hill on the crosswind plane. When two adjacent hills are in the frontrear arrangement with zero distance, the wind velocities on the front hill are very close to those on the isolated hill, while the wind velocities on the rear hill are much lower than those on the isolated hill. When two hills are in the leftright arrangement, the speedup effect at the top of the hill are slightly more significant than those on the isolated hill, and the speedup effect on the hill in the valley side are more significant than those on the isolated hill.
