Development of Direct Reduction CFD Mathematical Model:Midrex Reactor
World production of DRI has increased in the recent past due to the raise in industrial capacity.MIDREX reactors account nowadays for about 70% or more of this production.However,process reactions,operational parameters and raw materials behavior influence in the direct reduction reactor need to be further studied.Computational simulation has been an important tool for forecasting,developing and analyzing raw materials and operational parameters.This is mainly because the model answer is fast and after the model has been validated it has a low operational cost,since raw materials and fuels are not consumed.Another positive point is that there is no environmental impact given that all experiments are performed in a virtual environment.This work aims to present the development of a direct reduction CFD model focused on the MIDREX reactor.The mathematical modeling follows the continuum theory,where a collect of particles are considered identical and as such can be solved by transport phenomena equations.Momentum,mass and energy transport equation are solved simultaneously.The resulting discretized partial differential equations are solved using the finite volume method.The developed model is able to predict the behavior of MIDREX reactor associated to products and processes.The main results obtained by this model are profiles of temperature,pressure and chemical composition of gas and metallic materials; besides this it predicts metallization percentage of DRI among others operational parameters.
