摘要

摘要本文介绍了对蒸汽喷射器产生非线性弛豫压力振荡模式的实验研究结果。在振荡曲线的前缘检测到了高频衰减压力跃变。结果表明，在产生振荡时，喷射器的工作模式从超音速变为亚音速。对循环过程中的压力振荡过程进行了解释。工作蒸汽压力为 8-10 巴时，振荡幅度为 5-6 巴，频率为 5-20 赫兹。

A Pressure Oscillation Steam–Water Generator

The results of an experimental study of a steam jet injector in the mode of generating nonlinear pressure oscillations of a relaxation nature are presented. High-frequency decaying pressure jumps were detected on the leading edge of the oscillation curve. It is shown that, when exciting oscillations, the injector operating mode changes from supersonic to subsonic. An explanation of the pressure oscillation process during the cycle is given. With a working steam pressure of 8–10 bar, an oscillation amplitude of 5–6 bar at frequencies of 5–20 Hz was obtained.
