一维模型的树立。早在19 世纪,Zeuner-Rankin将气体动力学引进到干粉喷射器的研讨中,可是在核算时,因为选用一维核算理论,对混合压力和混合面积的处理上遇到了困难,致使动量方程得不到合理的求解。针对此疑问,1942 年,Keenan 和Neumann提出了两种假定:第一种假定两股流体在混合时截面积安稳不变(定常面积混合理论);第二种将两股流体合混合进程看做近似等压进程(等压混合理论),对喷射器规范进行了优化核算。随后,喷射器内的一维模仿模型大都是依据这两个理论树立的。可是因为两种理论在核算时假定了作业流体和混合流体具有一样热力学参数和分子量,核算精度不能满意实习生产中的需求,随后大批专家对其进行了修正完善。1951 年Holton研讨指出流体分子量对喷发系数的核算有首要的影响。Work 和Headrich 等专家也经过试验数据证明了这一点。
