Rotors with a novel structure for enhanced follow-up dynamic mixing

Abstract Nowadays, dynamic mixers are widely used in industry. But dynamic mixers have problems like low mixing efficiency and high mixing resistance. Therefore, many scholars are committed to improving the rotor inside the dynamic mixer to improve its working performance. In this paper, a new structure of spiral rotor with chamfer and perforation was designed for promoting the performance of the dynamic mixing equipment. We measured the pH value to find which rotor’s working performance is better. On this basis, a numerical simulation was conducted on the mixing angle of the two-phase fluid to explore the best working environment of the dynamic mixer. Experimental studies proved that the mixing effect of the new structure rotor was better. The simulation results showed that the mixing effect of the two-phase flow was better when it merged at 135°.
