通过摩擦系数λ和动量交换系数ｋ两种变量的分析，确定了多孔管摩擦系数λ和动量交换系数ｋ的分析表达式，在此基础上，求出了变系数变质量动量方程的分析解。常系数方程的解成为变系数方程解在动量修正项为０、摩阻修正项为１时的特殊形式。另外，变系数变质量动量方程的解，仅是多孔管的结构尺寸参数Ｅ和流动参数Ｒｅ的函数。这不仅在新分布器上的设计上，可以优化结构，确定分布器的工况稳定性和安全性，而且在在役分布器的校核上，可方便地模拟操作工况，确定最佳运行方案
Based on the analysis of the friction coefficient λ and the momentum exchange coefficient k, the analytical expression of the friction coefficient λ and the momentum exchange coefficient k of the porous tube was determined. Based on the analysis, the analytic solution of the variable mass momentum equation was obtained. The solution of the constant coefficient equation becomes a special form of the variable coefficient equation solution when the momentum correction term is 0 and the friction correction term is 1. In addition, the solution of the variable coefficient variable mass momentum equation is only a function of the structural dimension parameter E and the flow parameter Re of the porous tube. This not only in the design of the new sparger, you can optimize the structure, to determine the stability and safety of the sparger condition, and check in-service sparger, you can easily simulate the operating conditions to determine the best operation Program
