Effect of particle shape on catalyst deactivation using particle-resolved CFD simulations
Chemical Engineering Journal, 2019Abstract A method has been demonstrated using particle-resolved CFD simulations to simulate the transient catalyst deactivation due to carbon formation process and its impact on the particle properties. Preliminary simulations with cylindrical particles and propane dehydrogenation reactions showed higher carbon accumulation for the near-wall ...

Interface-resolved simulations of particles in active nematics
Physics of Fluids, 2023An accurate coarse-grained simulation of an active fluid is invaluable as a tool to understand its hydrodynamic behaviors. The study on the dynamics of particles immersed in an active fluid also requires accurate resolution of the fluid–particle interaction.

Fully resolved simulations of particle-turbulence interaction
Journal of Fluid Mechanics, 2005The interaction between a fixed particle and decaying homogeneous isotropic turbulence is studied numerically using an overset grid that provides resolution of all scales of fluid motion. A description of the numerical technique and validation of the solution procedure are presented.

Particle-Resolved Direct Numerical Simulations of Clay Particles in the Absence of Gravity.
2021<p>Flocculation processes of clay particles are usually influenced by settling effects due to gravity. This inhibits the investigation of the effects of cohesive forces in isolation and limits our understanding of flocculation processes over long time scales that are more common in aquatic environments.

Resolved Numerical Simulation of Particle Agglomeration
2015In numerous technical applications collisions between fine particles results in the formation of agglomerates, as for example in colloidal systems. The process of agglomerate formation is rather complex and depends on quite a number of interaction phenomena, such as particle collision rate, fluid dynamic interaction between colliding particles and ...

Pore-Resolving Simulations of Biomass Char Particle Combustion
Proceedings of the Combustion Institute, 2023Biomass char morphology affects combustion behavior at the particle scale for zone II conditions, in which both heterogeneous reaction and intra-particle diffusion govern the overall rate. Furthermore, particle-scale processes affect reactor-scale outputs, and reactor-scale simulations are sensitive to particle-scale models. However, most char particle

Embolus Transport Simulations with Fully Resolved Particle Surfaces
Cardiovascular Engineering and Technology, 2019There has been interest in recent work in using computational fluid dynamics with Lagrangian analysis to calculate the trajectory of emboli-like particles in the vasculature. While previous studies have provided an understanding of the hemodynamic factors determining the fates of such particles and their relationship to risk of stroke, most analyses ...

Particle-resolved simulations of antidune migration in supercritical flows
2023Antidunes are an important feature in the morphodynamics of streams over steep slopes. These bed forms are short-wave periodic disturbances that develop on the surface of loose granular beds in response to the interaction with supercritical and near-critical shallow, turbulent flows.
