The effects of virtual mass force and particle aspect ratio on orientation of slender particles in a stirred tank

Fundamental knowledge on particle orientation is important for processing and utilizing irregular shape particles. The orientation of slender particles influences the application of slender particles in many fluidization processes, such as pulp and paper, catalytic reaction, air pollution control. In this paper, the effects of virtual mass force and aspect ratio on the orientation of a slender particle in a particle cloud are studied. Virtual mass force, also called added mass force, apparent mass force, is a force due to the relative acceleration of the phases. The definition of virtual mass force is defined by Kuo and Wallis (1): Please click Additional Files below to see the full abstract
