Validation of hyaluronic acid-agar-based hydrogels as vitreous humor mimetics for in vitro drug and particle migration evaluations.

European journal of pharmaceutics and biopharmaceutics, 2020
Artificial vitreous humor holds immense potential for use in in vitro intravitreal drug delivery assays. In this study, we investigated rheological properties and drug or nanoparticle migration in hyaluronic acid (HA) - agar based hydrogels and compared ...

Shear-induced particle migration of semi-dilute and concentrated Brownian suspensions in both Poiseuille and circular Couette flow

, 2020
Neutrally buoyant colloids with small Reynolds numbers pose interesting challenges particularly when they undergo shear thinning and Brownian diffusion. Two basic flows including Poiseuille and Couette flows accompanying shear-induced particle migration ...

Equilibrium positions of the elasto-inertial particle migration in rectangular channel flow of Oldroyd-B viscoelastic fluids

Journal of Fluid Mechanics, 2019
In this paper, the lateral migration of a neutrally buoyant spherical particle in the pressure-driven rectangular channel flow of an Oldroyd-B fluid is numerically investigated with a fictitious domain method.

Minimizing the adverse effects of dust layer on the particle migration in electrostatic precipitator under various temperature

, 2020
The dust layer formed by charged particle deposition severely limited efficient and stable applications of electrostatic precipitators (ESPs). In this work, a modified method was established to study impacts of dust layer on space electric strength ...

Improvement of semi-resolved CFD-DEM model for seepage-induced fine-particle migration: Eliminate limitation on mesh refinement

Computers and geotechnics, 2019
The semi-resolved CFD-DEM model, proposed in our previous paper (Cheng et al., 2018) for the modelling of seepage-induced fine-particle migration through coarse skeleton in gap-graded soils, is improved through using Gaussian-based weighting function for

A semi-resolved CFD-DEM model for seepage-induced fine particle migration in gap-graded soils

Computers and geotechnics, 2018
A semi-resolved CFD-DEM model is proposed to model the seepage-induced fine particle migration within the gap-graded soils consisting of fine and coarse particles.

Analysis of aggregate particle migration properties during compaction process of asphalt mixture

Construction and Building Materials, 2019
Asphalt mixture is a kind of anisotropic multiphase granular materials. The compaction is the consequence of particle rolling and migratory permutation. To anatomize the migration properties of aggregates during the compaction process of asphalt mixture,

On the pressure-driven flow of suspensions: Particle migration in apparent yield-stress fluids

Journal of Non-Newtonian Fluid Mechanics, 2019
Suspensions of particles with viscoplastic characteristics are often found both in nature and industrial applications. However, in contrast with the case of suspensions in Newtonian fluids, the dynamics of shear-induced particle migration in yield-stress

Numerical simulations of particle migration in rectangular channel flow of Giesekus viscoelastic fluids

Journal of Non-Newtonian Fluid Mechanics, 2018
In this paper, the lateral migration of a neutrally buoyant spherical particle in a pressure-driven rectangular-shaped channel flow of Giesekus viscoelastic fluids is numerically investigated with a fictitious domain method. The particle trajectories are
