Simulation of Particle Beds with Combustion and Reduction in Steel Making Rotary Kilns

제철용 로터리 킬른 내의 연소 및 환원을 포함한 입자 거동 예측모사 해석

We simulate the particle bed motions with combustion and reduction in steel making rotary kilns. The particle bed motions are simulated by a Lagrangian approach called Discrete Phase Model (DPM). To reduce the number of tracking particles, the Coarse Grain Model (CGM) was applied. The model for particle motions showed good agreements with experimental results. In addition to the particle motion, the combustion and reduction simulation was performed. The combustion and reduction simulation can consider heat, mass and momentum transfer between the gas phase and particle beds.
