摘要

对开缝式SK型和可调涡旋2种新型静态混合器的结构参数进行数值模拟优化

并与传统SK型静态混合器进行比较。结果表明

间隙直径比为0.58的开缝式SK型静态混合器为最优结构;叶片圆心角为120°

曲率半径为400mm的三叶片涡旋发生器组成的可调涡旋静态混合器性能最优;可调涡旋静态混合器与开缝式SK型静态混合器的混合效果均优于传统SK型静态混合器

且可调涡旋静态混合器的混合速度更快。

Abstract

The structural parameters of two kinds of new mixers:the clearance SK static mixer and adjustable vortex static mixer were optimized by numerical simulation.Moreover

their optimized performance was compared with that of the conventional SK static mixer.The results indicate that

for the clearance SK static mixer

the optimal structural parameter is with width/diameter ratio(W/D)of 0.58.For the adjustable vortex static mixer

the one consists of three-blade vortex generator of which the blades' central angle is120°and the blade's curvature radius is 400 mm has the most great performance.Both the mixing effect of the adjustable vortex static mixer and the clearance SK static mixer are greater than that of the conventional SK static mixer.Furthermore

the mixing ratio of the adjustable vortex static mixer is the fastest.
