Abstract

Numerical analysis was carried out on the dripping and holdup behaviors in the lower part of a blast furnace for coke bed structures having different shapes; a discrete element method smoothed particle hydrodynamics scheme was used considering the size distribution immediately above the raceway. Even for coke beds with similar void fractions, the averaged-coke-shape factors such as and (D)2 give little clear correlation for holdup sites. Instead of averaged-coke-shape information, only the direct evaluation of the void shape of the packed bed can explicitly trace the holdup site.
