Despite the age of the process, the blast furnace remains critical to industrial ironmaking. With advances in analysis technologies and control systems, and economic pressure from competitive new ironmaking techniques, modern blast furnace operation has become more efficient. However, room still exists for improvement, particularly in the blast furnace raceway region. Further development requires better understanding of phenomena within the blast furnace, including heat transfer, mass transfer, chemical reactions, and multiphase flow. To that end, computational simulation and visualization, in multiple approaches, are increasingly used to explore blast furnace phenomena. Current computational approaches range from simplified tools designed for rapid turn‐around times to complex solvers intended to capture the movement of discrete particles within the furnace. This paper reviews recent current state‐of‐the‐art techniques for simulation and visualization of the blast furnace developed by the Center for Innovation through Visualization and Simulation (CIVS) at Purdue University Northwest (PNW), as well as an overview of other advanced techniques in the field.
