Numerical Modeling and Simulation of Dropped Granular Particles on the Curved Surface

Abstract

This study aims to present an approach for analyzing the performance of granular cosmetic adhesion by a numerical simulation using the uFlex particle. To ensure the viability of a numerical simulation, the effect of the process parameters on the dropping granular performance such as curve type, surface moisture level, and curve angle was evaluated. Results suggest that the humidity and curvature angle have significant effects on the density of cosmetic particles on the surface, while the other parameter have relatively small effects. Moreover, the effect of each parameter on the granular adhesion at the surface has been explained by utilizing the particle analysis after the collision. The simulation result shows the adhesion of granular particles with a curved surface leads to better performance under moist surfaces with a convex shape at the angle of 0 degrees. However, on all curvatures, worse adhesion performance under dry surfaces with convex shape.
