| Abstract: | 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. |
