“…The inclusion volume fraction for the 0–3 composite was generated using the random sequential adsorption algorithm. [ 53 , 54 , 55 ] This algorithm places the inclusion particles randomly within the representative volume element (RVE) zone and is adsorbed within the system if the particles don't interpenetrate with a previously adsorbed particle. Once a particle is adsorbed, its position remains fixed, and the next particles are randomly placed based on the previously placed particles until the final volume fraction of the inclusion within the RVE is achieved.…”

In the present numerical simulation work, effective elastic and piezoelectric properties are calculated and a comparative study is conducted on a cement matrix‐based piezocomposite with 0–3 and gyroid triply periodic minimal surface (TPMS) inclusions. The present study compares the effective properties of different piezoelectric materials having two different types of connectivity of the inclusions namely, 0–3 inclusions where the inclusions are physically separated from each other and are embedded within the matrix and the second one is TPMS inclusions having interpenetrating phase type connectivity. Effective properties are calculated for four different materials at five different volume fractions namely, 10%, 15%, 20%, 25%, and 30% volume fractions of inclusion by volume. In terms of effective properties and direct piezoelectric effect, TPMS piezocomposite is found to perform better compared to 0–3 piezocomposite. Lead‐free piezoelectric material 0.5Ba(Ca0.8Zr0.2)O3 − 0.5(Ba0.7Ca0.3)TiO3 demonstrates better performance compared to all other material inclusions studied. The present study attempts to highlight improved piezoelectric effective properties of lead‐free material‐based piezocomposites with TPMS inclusions.

“…Various methods have been developed to investigate it in the last few decades. The Random sequential adsorption (RSA) is one of the earliest models to simulate particles 10,11 . While to model a typical adsorption process, several strong assumptions have to be followed: all particles adsorb directly on the surface, external forces, hydrodynamics and diffusion are negligible 10,11 .…”

A hybrid pore-scale simulation method using Lattice-Boltzmann (LB) coupled with Langevin-Dynamics (LD) is proposed to investigate the transport physics of nanoparticles in microchannel. The controlling factors (i.e., ionic strength, particle diameter and Reynolds number) are investigated in the attachment process of NPs. It is observed that a threshold value of attachment efficiency exists as the ionic strength increases to about 0.01 M. Moreover, the ionic strength of aqueous phase has critical effect on the transport behavior of NPs. For the purpose of quantitatively characterizing the structure of NP suspensions under varying conditions, a general phase diagram including three flow patterns (isolated, transitional and clustered regime) is first proposed for NP suspension with specified ionic strength and Reynolds number. The outcomes of this work provide valuable insight on the critical importance of the particle size, ionic strength and hydrodynamic effects on the attachment and transport process of NPs in porous media

We have studied random sequential adsorption (RSA) of three classes of polygons with rounded corners: rectangles, isosceles triangles and orthogonal triangles. Using the algorithm that allows generating strictly saturated random packing, we have systematically determined the mean saturated packing fraction for RSA configurations built by these shapes. The main aim was to find out the figure that forms the densest random configuration. Although for rounded rectangles the packing fractions were lower than for discorectangles, the densities reached for some rounded isosceles and right triangles exceed the highest known two-dimensional packing fraction for configurations built of unoriented monodispersive objects. The microstructural properties of several packings were discussed in terms of the two-point density autocorrelation function.
