摘要：Acting as one of the core devices of sand blender, the stirring effect of sand blender stirring device had an important effect on the quality of the fracturing fluid and the effect of fracturing operation. It was necessary to study the power characteristics of the sand blender stirring device that because the power characteristics of the sand blender stirring device were closely related to the stirring effect. In this study, the CFD model of the sand blender stirring system was established by using the Computer Aided Design (CAD) and Computational Fluid Dynamics (CFD) software, the influence of the baffle number, the spacing of dual mixing impeller, the upper mixing impeller diameter and the lower mixing impeller diameter on the stirring power were analyzed based on this. The results shown that the baffle number and the spacing of the dual mixing impeller had less influence on the stirring power of the sand blender stirring device, but the upper and lower mixing impeller diameter had great influence on the stirring power of the sand blender stirring device. On the basis of the numerical simulation, the weight coefficients of the upper and lower impeller diameter and the equation of the stirring power were obtained by using the SPSS software to carry out nonlinear regression analysis. The NP-Recurve was obtained, according to the numerical simulation of different impeller rotational speed. The study results would provide reliable theoretical support for the calculation of the stirring power of the sand blender stirring device.
