设计了一种注气内管内径渐变的高粘度豆胶气泡雾化喷雾器,并应用流体分析软件,对喷雾器内部气液两相混合流体特性及其下游雾化进行了数值模拟研究。主要模拟了喷雾器内部气液两相流的速度场分布、压力场分布并分析了模拟结果。分析表明:在设计的气泡雾化喷雾器内部,豆基蛋白胶能够与空气进行很好地混合,其内部压力场分布、速度场分布符合流体力学的运动规律。模拟结果对以后的多相流流动分析以及气泡雾化的研究具有一定的指导意义。
A high-viscosity bean gum bubble atomizer with a gradual inner diameter injection was designed. The fluid analysis software was used to study the characteristics of the gas-liquid two-phase mixed fluid in the atomizer and its downstream atomization. Mainly simulate the velocity field distribution and pressure field distribution of gas-liquid two-phase flow in the atomizer and analyze the simulation results. The analysis shows that within the designed bubble atomizer, the soybean protein glue can mix well with the air, and the distribution of internal pressure field and velocity field accord with the law of fluid mechanics. The results of the simulation have certain guiding significance for the future multiphase flow analysis and bubble atomization research.
