射流微振荡器的设计与实验研究

摘要

A fluidic oscillator consisting of a bistable fluidic element and two chambers is proposed. 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 influencing the oscillating frequency, such as the supply air pressure, the length of feedback pipeline and the volume of the oscillating chamber. The working principle of the oscillator is analysed and provides experimental and theoretical evidence for its using.%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.
