Research on a rapid method for obtaining the matching point of the static operating pressure of a supersonic jet in a wind tunnel
Peng Liu, Jinglun Cai, Xuejing Shao, Hui Jin
Izvirni znanstveni članek
Oznake: supersonic jet;pressure matching;expansion wave;compression wave;
In the wind tunnel test, mismatched operating pressures can cause the jet flow field to produce expansion waves, compression waves, and wave interference. The current wind tunnel pressure matching study requires continuous adjustment of the operating pressure at the inlet and outlet to obtain an ide ...

Study on the trade-off mechanism between flow field uniformity and turbulent pressure pulsations in back-pressure matching for supersonic wind tunnels
Peng Liu, Jinglun Cai, Hui Jin, Yibing Yin, Ludi Kang, Xian Chen
Izvirni znanstveni članek
Oznake: supersonic wind tunnel;backpressure matching;flow field uniformity;pressure pulsation;shear layer;
Supersonic wind tunnel testing is critical for aircraft aerodynamic configuration validation, where test chamber flow uniformity and turbulent pressure pulsations are core determinants of test data reliability. Existing back-pressure matching studies only optimize flow uniformity as a single objecti ...
