摘要
设计了一种由双稳射流元件和振荡腔组成的射流振荡器,射流元件输出口经过振荡腔接回元件的控制口构成反馈。通过实验研究了供气压力、反馈管路长度和振荡腔容积等影响振荡频率的主要参数,同时分析了振荡器的工作机理,为射流振荡器的应用提供了理论和实验依据。
A fluidic oscillator consisting of a bistable fluidic element and two chambers is pro- posed. Each outlet of the fluidic element is connected with a chamber and feeds back to control channel. Experimental data with various survey pressure illustrate that the main parameters in- fluencing the oscillating frequency, such as the supply air pressure, the length of feedback pipe- line and the volume of the oscillating chamber. The working principle of the oscillator is analysed and provides experimental and theoretical evidence for its using.
