摘要
搭建设计直流式风力试验平台,使用皮托管在试验段不同位置及不同深处进行风流的速度,压力及温度测试,并采用蜂窝器和整流网对平台的流场品质进行改进,对于风流的均匀性及稳定性进行测试及比较,结果表明,改进后的直流式试验平台具有良好的风流流场,具备开展小模型的吹风试验的基本条件。
In this paper a complete design and construction of the straight flow low speed wind tunnel test platform is intro-duced, and the speed of the air flow, pressure, and temperature test with pitot tube in different locations and depth in the ex-perimental section are performed.The quality of the flow field with honeycomb device and rectified net is improved.Tested and compared on the uniformity and stability of the air field, the results show that the improved straight flow low speed wind tunnel test platform has good airflow flow field, which meets the basic requirement and can be carried out the simple experi-mental model test.
