“…5 (c and d). The decreased water absorption rate of neRA samples after 28 days curing age is thought to be related to the fact that NS and NT increased chemically bound water due to the higher hydration rate [27]. While the MIP results showed the evidenced that increase the dosage of NS and NT decrease the threshold pore diameter and this phenomenon directs significant properties for cement durability.…”

“…The fluid density and viscosity are set to 1.2 kg/m 3 and 1.8 × 10 −5 Pa•s, respectively. The densities of the CG particles are calculated by Equation (7) in the same manner as Table 1. Figure 5 shows the particle trajectories in the vortex flow field represented by the DEM with and without the SCG model.…”

“…Powder simulations are commonly utilized in numerous industrial fields such as food, medicine, and ceramics to control powder processes and comprehend the powder phenomena. A representative method for analyzing the powder behavior is the discrete element method (DEM) [1][2][3][4][5][6][7], and the coverage of the analysis region has been expanding [8][9][10][11][12]. In the DEM, the powder behavior is represented by solving Newton's motion equations of each particle composing the powder [13].…”

A new simpler coarse-grain model (SCG) for analyzing particle behaviors under fluid flow in a dilute system, by using a discrete element method (DEM), was developed to reduce calculation load. In the SCG model, coarse-grained (CG) particles were enlarged from original particles in the same way as the existing coarse-grain model; however, the modeling concept differed from the other models. The SCG model focused on the acceleration by the fluid drag force, and the CG particles’ acceleration coincided with that of the original particles. Consequently, the model imposed only the following simple rule: the product of particle density and squared particle diameter is constant. Thus, the model had features that can be easily implemented in the DEM simulation to comprehend the modeled physical phenomenon. The model was validated by comparing the behaviors of the CG particles with the original particles in the uniform and the vortex flow fields. Moreover, the usability of the SCG model on simulating real dilute systems was confirmed by representing the particle behavior in a classifier. Therefore, the particle behavior in dilute particle-concentration systems would be analyzed more simply with the SCG model.
