CFD Simulation of Co-Injection of Plastic Particles and Oil into a Blast Furnace Raceway

摘要

Basing on a CFD model for plastic particle injection published by the authors an extended simulation model is developed. The new model makes use of the capability to predict the raceway shape using a new porous media approach. This allows to avoid the high computational effort of a full Eulerian multiphase formulation and incorporates a simplified reaction mechanism for calculation of the high temperature conversion of injected materials. In addition the ability to handle the simultaneous injection of multicomponent droplets like heavy fuel oil and tar has been incorporated.
