Integrated supersonic wind tunnel nozzle
Chinese Journal of Aeronautics, 2019 Abstract In supersonic wind tunnels, the airflow at the exit of a convergent-divergent nozzle is affected by the connection between the nozzle and test section, because the connection is a source of disturbance for supersonic flow and the source of disturbance generated by this disturbance propagates downstream. In order to avoid the disturbance, the

A Compliant Wall, Supersonic Wind Tunnel [PDF]
The Aeronautical Journal, 1978 The self-correcting wind tunnel has attracted considerable interest in recent years as a concept for achieving minimum wall interference in a wind tunnel. Sears, et al., have presented an authoritative account which is recommended to the reader. Among their important conclusions is that a perforated wind tunnel wall (with control of the pressures in ...

Nozzle Geometry-Induced Vortices in Supersonic Wind Tunnels
AIAA Journal, 2021 Streamwise-coherent structures were observed in schlieren images of a Mach 2.5 flow in an empty supersonic wind tunnel with rectangular cross-section. These features are studied using RANS computations in combination with wind tunnel experiments. The structures are identified as regions of streamwise vorticity embedded in the sidewall boundary layers ...
