摘要: 采用涡量-流函数法对波形板内的流场进行了数值模拟。采用单颗粒动力学模型,即SPD模型,对波形板内水滴的运动轨迹进行了数值研究,并对波形板分离器的分离效率进行了计算,将计算结果与试验结果进行了比较,讨论了波形板汽水分离器的结构参数对工作性能的影响。研究结果表明,对波形板进行板型设计时,偏折角不宜大于45°;波形板分离器进口湿度较小时可以优先选用无疏水槽的波形板分离元件,如果湿度较大,则要优先选用有疏水槽的分离元件。

Abstract: The flow field in the zigzag-corrugated baffle separator was calculated using vorticity-velocity algorithm. The tracks of water droplets in the flow field were calculated using SPD model. And the separating efficiency and pressure reduction were calculated too. By comparing calculation and experiment results, the mechanism of zigzag-corrugated baffle separator was gotten. The research result is that,it is suitable to the leading angle equal to 45degree when design zigzag-corrugated baffle; And if the steam with great moisture flow into Separator, the groove zigzag-corrugated baffle should be adopt firstly.
