介绍了汕头大学大气边界层风洞和其配制的测控系统及流场校测结果。汕大风洞主要做建筑物的抗风实验和风环境实验。为模拟大气边界层,实验段较长,实验模型放在实验段后部。为减小轴向静压梯度顶板高度分段可调。风速比航空凤洞低。配置了建筑物测压和测力实验所需的电子压力扫描测量系统和高频底座天平。流场校测表明,该风洞的气动性能已达合同规定的指标。
Introduced the Shantou University atmospheric boundary layer wind tunnel and its preparation of measurement and control system and flow field test results. Wind tunnel in Shantou University mainly wind resistance experiment and wind environment experiment. In order to simulate the atmospheric boundary layer, the experimental section is longer and the experimental model is placed at the back of the experimental section. To reduce the axial static pressure gradient roof height adjustable. The wind speed is lower than the air hole. Equipped with electronic pressure-scan measurement system and high-frequency base balance required for building manometry and force-measuring experiments. Flow field tests show that the aerodynamic performance of the wind tunnel has reached the contractual targets.
