对旋叶式汽水分离器叶片区域液滴受力进行合理简化,得到旋叶式分离器叶片区域液滴动力学方程。利用数值模拟对比不同液滴直径、空气入口流速和叶片升角时,液滴通过叶片区、液滴撞击叶片和液滴撞击筒壁份额的变化。当液滴尺寸增大、空气入口流速增大或叶片升角减小时,液滴撞击叶片份额呈现增加的趋势,叶片升角对结果的影响不大。液滴曳力与惯性力的比值在时间上的积累越大,液滴越不容易撞击到叶片上。
The droplet force in the blade area of rotary vane separator is reasonably simplified, and the droplet dynamics equation in the blade area of rotary vane separator is obtained. Numerical simulations were performed to compare the changes of the droplet fractions, droplet impinging vanes and droplet impinging tube wall fraction on different droplet diameters, air inlet velocity and blade angle. When the droplet size increases, the air inlet velocity increases or the blade angle decreases, the droplet impact on the blade tends to increase, and the blade angle has little effect on the result. The larger the ratio of drop drag force to inertial force accumulated over time, the less likely it is for the drop to hit the blade.
