Numerical Simulation Of Propellant Slurry Stirring Process

Abstract

Abstract Taking the mixing process of medicine slurry in kneader as the research object, the finite element analysis method was used to simulate the law and characteristics of TCM slurry flow in the mixing process. The simulation results show that the telocentric blade plays an important role in the stirring process. The scraping area of telecentric blades and the kneading area of two blades are the main kneading areas. The flow direction of slurry does not change at different speeds, and the velocity has a linear relationship with the blade speed. The axial conveying capacity is the best at the central horizontal section of the mixing kettle. When the rotational speed increases, the shear stress and viscous heat loss rate increase, and the viscosity decreases.
