Abstract

A simulation of gas flow in a blast furnace was conducted by using the finite element method with quadratic elements. Vectorial form of the Ergun's equation was used for the equation of motion of gas in the packed bed. According to the variational principle, the discretization equation was derived from the equation of motion together with the equation of continuity. As for the infurnace structures required for numerical calculation, layered structure of ore and coke, cohesive layer and raceway zone were taken into account. Simulation computations were carried out for some different configurations of cohesive zone and/or some different distributions of particle size. A numerical computation was performed to obtain the distributions of gas flow and pressure for the case in which the whole ore layer consisted of double layers of different particle size.
