Direct simulation of drying colloidal suspension on substrate using immersed free surface model
TL;DR: A key issue of the present method is the immersed free surface model proposed by the authors, which enables us to estimate accurately and efficiently capillary forces exerted on particles on a free surface.

TL;DR: In this article, numerical simulations of the dispersion and aggregation behavior of surface-modified Al2O3 nanoparticles in toluene under shear flow are performed, where the motion of nanoparticles is calculated based on Newton's equation of motion, and the flow of the solvent is determined by solving the Landau-LifshitzNavier-Stokes equation.

Experimental and theoretical studies on compressive deformation characteristics of particle aggregates in water
TL;DR: In this paper, the compressive deformation characteristics of a single aggregate of polystyrene particles were studied both experimentally and theoretically Experimental apparatus to measure the mechanical characteristics of the single aggregate with in situ observation of the compression behavior of the aggregate was constructed, and the time variations of compressive force and deformation behavior of aggregate during simple compression were investigated in addition, discrete element method (DEM) simulations were carried out to numerically demonstrate the compression behaviour of an aggregate between two planes.
