摘要
通过实验研究证明了用主流阻尼器快速调节半开口直流式低速风洞的实验风速的可行性。实验还考察了驻室容积、风扇转速等因素对调速加速度的影响,为稳态扫描环境模拟试验装置快速变速系统提供了必要的设计参数。
For a low speed blow down wind tunnel with semi-open test section, the effectiveness of main flow damper in rapidly changing test velocity is verified through experimental research. Influences of plenum volume and fan rotation speed on acceleration are also investigated. The results have been used to design the velocity regulating system for a circumstance simulation facility for steady scanning.
