Abstract
A Lagrangian simulation technique to predict the trajectories of solid particles in turbulent flow of a liquid continuous phase is presented. The method assumes one-way coupling, i.e., influence of particle on the flow is neglected. Mass loading ratio is as low as the order of 1 × 10−5. Drag, Magnus lift, Saffman lift across the flow direction, and gravitational forces are considered. Particle-particle and particle-wall interactions have been counted. On the other hand, turbulent fluctuation effects are neglected. Particle trajectories in a zigzag channel are computed. Effects of particle size, particle drop position, zigzag angle of the channel and inlet flow Reynolds number have been investigated. Particle size and/or density and initial particle placement position have been found to have significant effect on the trajectories.
