Abstract：Numerical simulations of the particle dynamics were performed by Fluent software of computational fluid mechanics to characterize the separation efficiency of various structure parameters of volute cyclone. The prediction models of separation efficiency of volute cyclone were obtained based on the response surface method. The results show that the vortex finder diameter has obvious influence on the separation efficiency. With the decrease of vortex finder diameter, the separation efficiency significantly increases. The influence of cone bottom diameter is greater. The larger the cone bottom diameter is, the higher the separation efficiency is. The effect of cylinder height on separation efficiency is relatively stronger. With the increase of the lower cylinder height, the separation efficiency increases initially and then decreases. The prediction value is consistent with the value of numerical simulation which is indicated by comparing the separation efficiency of the optimization model.
