合成喷是一种新型喷 ,了解它的形成机理对其设计和应用起着重要的作用。该文讨论了液体合成喷和气体合成喷的形成特点并建立了各自相应的数学物理模型。利用小扰动模型解释了大空间液体合成喷形成的原因 ,通过一个简单的热力学模型探讨了气体合成喷的形成机理。分析认为 :液体合成喷的产生主要是空化效应的结果 ,而气体合成喷的形成机制类似于微型压缩机。与他人实验结果的对比表明 :上述二种合成喷的机理分析是合理的
Synthetic spray is a new type of spray, understand its formation mechanism for its design and application plays an important role. In this paper, the forming characteristics of liquid synthetic spray and gas synthetic spray are discussed and corresponding mathematical physical models are established. The small disturbance model is used to explain the reason of formation of large space liquid injection. The formation mechanism of gas injection is discussed through a simple thermodynamic model. The analysis shows that: the liquid synthetic spray is mainly produced by the cavitation effect, and the formation mechanism of the gas synthetic spray is similar to the miniature compressor. Comparison with other experimental results show that: the above two synthetic jet mechanism analysis is reasonable
