Modeling of air flow through sinter mix bed

Abstract

The present work relates the flow of air through a packed sinter mix bed to the pressure drop using the Ergun’s Equation. The velocity of air infiltration across the sinter mix charged into a pot was measured at different suction pressures. The parameters, void fraction and equivalent spherical diameter were calculated using the pressure drop and air velocity relationship. These have been interpreted in terms of the process variables vis-à-vis the mix permeability The validity of the Ergun’s equation was checked while comparing the observed pressure drop with the computed one obtained by fitting the above parameters in the equations.
