Abstract

Abstract: To improve the mixing performance of fracturing sand mixing device, a method that combines the orthogonal test and CFD numerical simulation was adopted to study the influence of primary geometric dimensions of mixing impellers on mixing time. The mixing time was used as the experimental index, and the structural features of mixing impellers were considered. The optimal structural parameters of the impellers of mixing devices were obtained, providing theoretical support for the structural optimization of the mixing impellers. The results showed that the variation of the geometric dimensions of mixing impellers influenced the mixing time. The diameter of the upper impeller had the greatest influence, followed by the diameter of the lower impeller as well as the diameter ratio between the lower draft tube to the lower impeller, whereas the diameter ratio between the upper draft tube to the upper impeller had a relatively minor influence. The optimal configuration for the geometric dimensions of mixing impellers yielded the shortest mixing time of 11.0 s.

Key words: fracturing, sand mixing, mixing device, mixing impeller, mixing time
