主 题：Suspension Highly concentrated slurry Electrical resistance tomography Computational fluid dynamics Homogeneity
摘 要：Many chemical engineering processes deal with dense suspensions of large solid particles in *** of such systems are difficult to predict because the many solid particles strongly affect the hydrodynamics produced by the *** main objective was to assess the performances of the PBT,A310,and PF3 impellers in agitating highly concentrated slurries of large *** resistance tomography was used to determine the degree of homogeneity and solid particle distribution within the slurry *** gain more insight into the complex behavior of the flow inside the dense suspensions,computational fluid dynamics simulations were conducted using a Eulerian-Eulerian multiphase *** qualitative and quantitative analyses were performed to obtain details on the dispersed solid phase distribution and its effect on the mixing *** found that the PBT impeller was the most efficient in terms of consuming power and generating velocity and turbulent kinetic energy within the mixing tank.
