气液两相流动数学模型在同心式泡沫发生器优化中的应用

The Application of Gas-liquid Two-phase Flow Mathematic Model on the Concentric Type Foam Generator Optimization

为了给冲砂洗井泡沫的制备和关键工艺设备研制提供理论基础,应用气液两相流动数学模型对泡沫发生器内部流场进行模拟计算.通过改变出气管顶端的倾角和出气管至入口变径腔距离来分析泡沫发生器内部速度和压力对流场影响,得到更科学合理的泡沫发生器结构参数.

In order to provide theoretical basis for sand washing bubble production and development of the key process equipment, this paper simulate the inner flow field of the foam generatorwithgas-liquid two-phase flow mathematic model. By changing the angle at the top of thepipe trachea and the trachea to inlet diameter cavity distance to analysis the influence of the internal velocity and pressureon the flow field, and obtain more scientific and reasonable structure parameters of foam generator.
