摘要:

为了探究航空射流振荡器的流动特性，设计了某型航空高频射流振荡器，通过高频动态压力传感器测量及二维非定常数值模拟方法，对其频率-压力响应特性、速度-压力响应特性及内部流动特性进行了实验与数值研究。研究结果表明：(1)在给定几何尺寸的射流振荡器中，研究发现射流喷嘴处压力振荡频率是反馈回路处的2倍。(2)在定范围内，随着进出口压比的增加，射流振荡器的射流振荡幅度也逐渐增强。(3)在一定范围内，随着入口流量的增加，射流振荡频率线性增加。这些研究结果为射流振荡器的设计和应用提供了重要的学术和工程指导，有助于工程师更好地理解和控制该器件的性能，以满足各种航空应用领域的需求。

Abstract:

To investigate the flow characteristics of an aviation jet oscillator, a high-frequency aviation jet oscillator was designed. The frequency-pressure response characteristics, velocity-pressure response characteristics, and internal flow characteristics were studied experimentally and numerically using high-frequency dynamic pressure sensors and two-dimensional unsteady numerical simulation methods. The research results show that: (1) In a jet oscillator with given geometric dimensions, the pressure oscillation frequency at the jet nozzle is twice that at the feedback loop. (2) Within a certain range, as the inlet-to-outlet pressure ratio increases, the oscillation amplitude of the jet oscillator also gradually increases. (3) Within a certain range, as the inlet flow rate increases, the jet oscillation frequency increases linearly. These findings provide important academic and engineering guidance for the design and application of jet oscillators, helping engineers better understand and control the performance of such devices to meet the needs of various aviation applications.
