Abstract: This paper introduced the structural principle of the servo dynamic mixer. The images of the distribution of dispersion phase of glycerol on the axial cross section in the plane tube and in the servo dynamic mixer were obtained by photographic technique. Mixture multiphase model and RNG k-ε model were chosen in CFD modeling to obtain the cloud chart of the distribution phase and the variation coefficient of glycerol. The results of the distribution of glycerol in the plane tube obtained in the experimental study and numerical modeling agreed well with each other, proving the rationality of the numerical modeling. The experimental results showed that the servo dynamic mixer had an effect of partition-segregation, disturbance, and friction-blend on the dispersed phase. The variation coefficient of glycerol obtained by the way of CFD modeling showed that the servo dynamic mixer had excellent performance on mixing.
