Simulations of Different Solid-liquid Suspension Flow Patterns in Pipelines using Lagrangian-Lagrangian Method

Particle based methods can be used for both of the simulations of solid and fluid phases in multiphase medium. Discrete-element method (DEM) and the smoothed particle hydrodynamics (SPH) are two of them, typically used for solid phase and fluid phase respectively. This paper presents a computational method combining these two methods for solid-fluid flows in pipelines. These two phases are coupled by using an improved model from a reported Lagrangian-Eulerian method.
