Comparison among Turbulence Models for a Novel Static Circulating Jet Mixer

摘要：

Three turbulent models, standard k-ε model, realizable k-ε model and SST k-ω model, are proposed to calculate the distribution of the flow field in a novel static circulating jet mixer. The results show that the SST k-ω model can depict truly the fluid motion in the novel jet mixer from the velocity vector distribution. The k-c Standard model overestimates k in the wall and the bulk zones. Comparing the numerical models, the SST k-ω model gives better results than the other k-ε models at the same Reynold number.
