Abstract: To address the problems of low mixing efficiency and uneven dispersion of additives in the mixing displacement tank of cementing equipment, this paper uses CFD simulation to analyse the influence of impeller parameters on flow field characteristics and optimise the mixing performance. This paper takes the cementing equipment stirring displacement tank as the research object and uses computational fluid dynamics (CFD) to analyse the mixing effect of the stirring displacement tank on liquid additives and clean water. The distribution results of liquid additives, clean water, and fluids with a flow rate greater than 0.5 m/s are obtained. Comparative analysis of the simulation results showed that increasing the rotational speed is the best way to enhance the fluidity of the fluid in the tank. The inclined impeller is conducive to the lateral flow of the fluid, while the vertically arranged impeller is conducive to the vertical upward movement of the fluid.

Keywords: agitated displacement tank; agitating performance; rotational speed; impeller; CFD simulation; fluid mixing performance.
