摘要
The investigation on the flow field and dispersion characteristics of resonant sound mixing is of great significance for the dispersion mixing of heat sensitive superfine materials. In order to simulate the flow field and dispersion characteristics of resonant sound mixing, a gas-liquid-solid three-phase flow model based on CLSVOF-DPM was established, and the mixing uniformity was evaluated by the standard deviation of the number of particles in different regions. The CLSVOF model solves the gas-liquid interface and the dispersion flow field. The DPM model tracks the particle position and realizes the bidirectional coupling of the CLSVOF model and the DPM model through the momentum exchange between the continuous phase and the particles. The calculation results showed that the turbulent flow is diffused downward from the vicinity of the liquid surface when the acceleration exceeds 30g, where g is the gravitational acceleration. The liquid filling ratio and the feeding position affect the dispersion efficiency and quality. The uniform dispersion time is the shortest when the excitation acceleration is 40g. Finally, experiments were carried out using a self-made resonance acoustic hybrid prototype, and the flow field vector under different excitation accelerations was recorded using the PIV system, and the radial velocity distributions of the experiments and simulations were compared. The experimental results prove the accuracy of the simulation ones. © 2019, Chemical Industry Press. All right reserved.
