Simulation of granular in two dimensions: The effect of particle velocity on rigid wall boundary

Abstract

The various setting of granular systems becomes an interesting and important thing to learn another granular-like system. Each system can represent different physical meaning. In this work, we perform two dimensions simulations of granular on the rigid wall. The varying initial velocities generate for each particle. We used two sets of the rigid wall, straight and inclined wall. The interaction of particle-particle and wall-particles used frictionless rigid body interaction. From the simulation result, observed that the small increment of a given velocity affected the reached maximum height particle as rapidly. The inclined wall indicates the less number of particles that pass through the wall. Future work can implement these results such as on granular energy damping.

Development and evaluation of granular simulation for integrating computational thinking into computational physics courses

“…Students were also encouraged to describe and organize data with appropriate graphs, charts, words, or images as part of CT (Hsu et al, 2018). For example, the resulting process in the Wavebreak Simulation was observed in increasing a given velocity that affects the reached maximum height particle and convergence of the granular particle movement (Muliyati et al, 2018). In addition, learning aims to describe the complex problems of the application into a description in the form of algorithmic notions of the flow of control (Grover & Pea, 2013).…”

“…Granular is one of the fastest-growing simulations to observe microscopic scale distribution phenomena in physics, e.g., pressure (Matuttis, 1998), and macro view, e.g., waves (Muliyati et al, 2018), or powder and pores (Muliyati et al, 2019). Granular simulations can be applied to almost all physics materials, making them suitable as teaching materials for lectures in computational physics courses.…”

The Simulation of Granular Particle on Dry and Moisturized Porous Horizontal Surfaces

“…So it needs further research to find additional components that can reduce the coefficient of restitution in the use of cosmetics and maximize the process of applying cosmetics to the skin. In further research, this simulation must also consider the density of particles that fall earlier because if the granules overlap with each other, a granular buoyancy force will be created, which has similar characteristics to the fluid buoyancy force [43], also necessary to consider the initial velocity of the fall because the granular will experience a reverse velocity in accordance with the contact plane when it falls in the pore hole conditions [44].…”
