A solid flow model for blast furnace based on hypo-plasticity theory

Abstract : A finite element method has been used to model solid flow inside a cold blast furnace, based on a hypo-plastic constitutive equation. This equation was calibrated with data obtained from simple soil mechanics tests on coke material. The steady state velocity and stress fields were determined after an iterative enmeshment procedure. The most significant results include the computed shapes of the deadman zone and the active and passive state regions, the transition between plug flow in the shaft and funnel flow in the bosh, and the void ratio distribution fields.
