“…One of the solutions to this drawback of the EL method is the Multi-Phase Particle-In-Cell (MP-PIC) method, which models the particle-particle interactions by employing a particle stress term in the equation of particles motion [20,21]. The MP-PIC method has been successfully implemented in simulating gas-solid flows in coal gasifier systems [22], pneumatic conveying flows [23], and fluidized beds [24][25][26].…”

“…The effect of normal-to-wall momentum retention coefficient on the results from CPFD simulations is provided in the supplementary material (section 4). The choice of particle-wall momentum retention factors is important for systems where the interactions between particles and walls are dominating such as particle transport pipes [23]. A diffuse bounce index of 5 is chosen for the particle-wall collision meaning that particles would have a scattered angle distribution after hitting the wall.…”

“…The experimental cases were simulated by using a computational particle fluid dynamics (CPFD) numerical scheme incorporated with the multiphase-particle-in-cell (MP-PIC) method. The model equations can be found elsewhere [9]. The CPFD numerical methodology incorporated in the commercially available Barracuda 17.0.3 code was used as the platform for the modeling and simulations.…”

“…A normal-to-wall momentum retention of 0.95, a tangent-to-wall momentum retention of 0.87, and a particle-particle restitution coefficient of 0.98 were used for the current simulations. Previous studies show that the effect of normal-to-wall momentum retention and the particle-particle restitution coefficient on predictions of pneumatic conveying characteristics is not significant, therefore these parameters were selected in a reasonable range according to the previous literature [9]. However, the tangent-to-wall momentum retention was calibrated for the pneumatic conveying system used in the present study.…”

Investigation of the possibility of using a pneumatic conveying technique for the transportation of dry drill cuttings is the main objective of this study. Both pilot‐scale experimental and simulation approaches were carried out for sand, which was used as a model material that mimics the properties of dry drill cuttings. Simulations based on the multiphase particle‐in‐cell method, which is a Eulerian‐Lagrangian model, were used to predict the pressure drop, and the predictions are in good agreement with the experimental results. Both approaches supported the possibility of using a pneumatic conveying technique for the transportation of dry drill cuttings under the tested conditions. The study provides the foundation for further analysis of the pneumatic conveyance of wet drill cuttings.

This paper presents a review of numerical models for simulation of gas-solid flow in bypass pneumatic conveying. The kinetic theory, conventional frictionalkinetic model and a new modified frictional-kinetic model are described in some detail. The experimental results for pressure drops based on a number of test cases are presented and compared with numerical results obtained with different numerical models. The convergences of the modified frictional-kinetic model with different values of constants are also illustrated. Moreover, the fluidisation charts of different materials with flow mode boundaries are presented to provide guidance on what frictional approach to use for Computational Fluid Dynamics (CFD) analysis of gas-solid flow in a bypass pneumatic conveying system. Furthermore, a flow chart for the CFD simulation methodology of bypass pneumatic conveying is demonstrated. These outcomes and the associated design guidelines could assist in choosing the most appropriate models for simulation of pneumatic conveying.
