Abstract:Triboelectrification of insulative granular system is a common phenomenon yet still not fully understood. Recent industrial and environmental processing technologies demand more comprehensive knowledge on tribo-charge within the flowing granular systems. Based on high-energy state electron hypothesis, here we develop an analytical model to predict the triboelectric charge distribution among particle systems. Particle size dependence of the tribo-charge is revealed, and influence of size range on the tribo-charge probability is evaluated. While the net tribo-charge of an individual particle is unpredictable, an interesting upper bound for the tribo-charge is found. Particle dynamic simulation is also carried out to study the charge transferring within the particle colliding process, which verifies the analytical prediction result. | |||
