| Abstract: |
| In this study，the physics，mathematics and finite element models for mixing field of counter-rotating twin rotor and co-rotating twin rotor mixers were established,and three-dimensional isothermal flow field simulation of mixer was performed by a computational fluid dynamics software Fluent.The mixing performance of the counter-rotating and co-rotating mixers，including dispersive mixing property and distributive mixing property were quantitatively studied and compared through analysis of the simulation results and statistical results of the trajectories of the large amount of particles.It was indicated that the dispersive mixing property in counter-rotating rotor mixer was better,and the distributive mixing properties from both counter-rotating rotor and co-rotating rotor mixers were similar. |
