Steady energy transfer dependence granular temperature on single bouncing granular particle
arXiv:1106.1772
Abstract
Simulation of a system consisted of free particle bouncing on a vertically vibrated based is performed. Two different states, which are steady and unsteady energy transfer state are found. The vibrating based is hold at constant vibration frequency as the vibration amplitude varied. Sinusoidal form is used. Granular temperature as function of based velocity and coefficient of restitution is used but shown no role in determining energy transfer state of the system. Peak of free particle trajectory around value 20 seperate region of the two states.
