Abstract Due to the complexity of flow field in high shear mixer, it is very difficult to measure the flow field in full three-dimensional. CFD simulation has become a powerful means in mixer research. In this study, large eddy simulation (LES) was used to simulate the single-phase flow field of a pilot scale in-line high shear mixer with ultra-fine teeth. The research results show that with the increase of the stator tooth thickness, the turbulence intensity and eddy current intensity around the outermost stator increase slightly, and the shear rate area with a larger value change slightly. This means that the stator tooth thickness has a slight effect on the flow field. These results provide important guidance for the design and optimization of high shear mixer structure.
