Experimental Investigation of Synthetic Fines Injection for Enhanced Residual CO2 Trapping during CO2 sequestration
… to enhancing residual CO2 trapping by injecting particles carried by the injected CO2. Natural fines migration can enhance residual CO₂ trapping through pore-throat blockage; however, this mechanism is mainly limited to clay-bearing sandstones containing mobile fines generated in situ. In …

A Computational Framework for Fluid-Thermal Coupling of Particle Deposits
… sand deposits and their surrounding fluid. Particle deposits that form in gas turbine engines and industrial burners, can change flow dynamics and heat transfer, leading to performance degradation and impacting durability. The proposed coupled framework allows insight into the coupled …

Modeling the Effect of Particle Diameter and Density on Dispersion in an Axisymmetric Turbulent Jet
Creating effective models predicting particle entrainment behavior within axisymmetric turbulent jets is of significant interest to many areas of study. Research into multiphase flows within turbulent structures has primarily focused on specific geometries for a target application, with little …

Two dimensional particle-in-cell simulation model for Hall type thrusters
… space and three dimensional in phase space, particle-in-cell (PIC) formulation for simulation of the plasma, while a separate model accounted for particle collisions, using Argon-electron elastic, excitation and ionization cross-sections. The collision model used an electron-neutral collision …
