摘要

Abstract

The radial multiple jets-in-crossflow mixing structure (RMJCMS) is extensively used in industrial manufacture. In this research

the effects of thickness of injection ring on mixing performance and factors influencing the mixing performance of RMJCMS were discussed based on the results of computational fluid dynamics. The simulation results showed that the dimensionless mixing distance

with the increase of the thickness of injection ring

drops from 1.1 to 0.18 first and then increases to 0.27 while the uniformity of flux monotonously improves

manifesting that the consistency of flux is not the single element determining the mixing performance. Analyzing the simulation results

a conclusion was drawn that the consistency of flux

penetration mode and interaction among injection flows which can be altered by adjusting the thickness of injection ring

determine the mixing performance of RMJCMS jointly. That is to say

in RMJCMS an injection ring with a suitable thickness can realize the function of injection and rectification simultaneously

which not only improves the mixing performance but also reduces the complexity of RMJCMS as well.
