Discrete Element Method in Projectile Motion Modelling on Supersonic Velocities

Fluid Properties Effects on Sand Production using Discrete Element Method

Oil production may be accompanied by Sand Production (SP) in the weak sandstone reservoirs. Fluid flow is an important factor in transporting the separated grains and completing the SP mechanism. In this paper, the effect of fluid parameters, fluid flow, and fluid pressure on the SP is investigated by applying the Discrete Element Method (DEM). Parametric studies show that fluid velocity is red...

Projectile Motion

The steel ball will be launched horizontally by being released at a certain height on the ramp. It will then fall to the floor and make a mark on the landing paper. The horizontal distance from take-off to landing, x, is proportional to the initial horizontal velocity, v0, of the ball. The distance, x, can be measured with the meter stick. By using the SALT®, photogate and computer, the time ca...

Simulation of High-velocity Penetration for Rigid Projectile into Plain Concrete Target using Discrete Element Method

Projectile Motion

Introduction: A projectile is a body in free fall that is subject only to the forces of gravity (9.81ms⎯2) and air resistance. An object must be dropped from a height, thrown vertically upwards or thrown at an angle to be considered a projectile. The path followed by a projectile is known as a trajectory. If gravity were not present, a projectile would travel in a constant straight line. Howeve...

Projectile Motion in Real Life

Projectile motion is a fundamental concept in basic physics courses. The often used simplified calculations, where air resistance is neglected, are obviously not relevant for many real life events. Using a video camera and computer software, students can investigate the influence of air resistance on for instance the trajectory of a football. The video sequences are digitised and the xand y-pos...
