THE EFFECT OF THE COEFFICIENT OF RESTITUTION TO THE PARTICLE COLLECTION EFFICIENCY DURING THE PROCESS OF MAGNETIC FILTRATION - NUMERICAL APPROACH

Abstract

In the present study, the effect of the coefficient of restitution to the particle collection efficiency of magnetic filter during magnetic filtration of a fluid will be examined. Initially, are described the available mathematical models that give efficiency of magnetic filtration in relation to various parameters and physical quantities. Also, the role of coefficient of restitution in the magnetic filtration models will be reported. Furthermore, is formulated the basic equation that examines the change of filtration efficiency with regard to the coefficient of restitution. In the last step, a numerical example with given values from a real magnetic filter will be applied and the characteristic curves of magnetic filter will be drawn. The general conclusion that we have is that as the coefficient of restitution increases, the efficiency of magnetic filter decreases. The efficiency of magnetic filter converges in the same value, when there is elastic collision of a filtered particle.
