Abstract
A mathematical model employing the discrete element method is used to study the stratification of particles during jigging. This model is used to simulate jigging of binary as well as ternary particles. In particular, effect of amplitude and frequency of pulsation on the stratification behavior of the particles is analyzed. The existence of an optimal condition in terms of amplitude and frequency of pulsation is established. Furthermore, the pulsation of fluid is controlled to generate different waveforms and its effect in turn on the stratification of the particles is investigated. It is shown that the numerical results correlate well with the available data in the literature.
