Internal flow numerical simulation analysis of coagulation mixing
混凝搅拌内部流场数值模拟分析

Through the numerical simulation of internal flow field for the round mixing container,the turbulence velocity field,turbulent dissipation rate and turbulence kinetic energy were analyzed for the flow changes of two-dimensional space in the container,the influence of particle coagulation collisions and the floc growth in the mixing process.For the round mixing container’s shortcomings,the experiment put forward a series of improved models: circular baffle,square glass,polygon glass,round angle glass and square spoiler model,then compared their internal flow field changes under different rotating speed.The results show that under the same cross-sectional area,the round angle model is more conducive to collision of particles bond and the growth of floc.
