【摘要】 作者从理论上提出了一个分析附壁型射流振荡器流量计振荡机理的数学模型,并发展了一个分析射流切换机理的新方法.理论分析表明,在高雷诺数下,斯特劳赫数是保持常数的,且振荡频率和流量之间能很好地保持线性关系,实验结果证明了这一点.更多还原

【Abstract】 The authors put forward theoretically a mathematical model for the mechanism of oscillations in Fluidic Oscillator Floweter, and developed a new method to analyze the mechanism of wall-jet Switches. Theoretical analysis has shown that Strouhal number is a constant, if Reynolds number is larger. And a fine linear relation may thus be kept between the flow rate and the frequency of oscillations, as has been proved by the experiments更多还原
