Explosions of molten aluminum and water are a potential, very serious safety risk in aluminum casthouses. Although prevention of these explosions is of paramount importance, understanding the overpressure resulting from an explosion is important to the design of blast-proof control rooms and protection of other equipment. Overpressure has traditionally been assessed using a simplistic principle of decreasing overpressure with distance, which neglects the significant, complex interactions of the blast wave with walls and other bodies. Computational fluid dynamics (CFD) modeling presents a method to analyze the problem in three dimensions. Blast analysis of a full casthouse with a conventional, commercial CFD code can be time-prohibitive. This paper presents a methodology to predict overpressure due to a molten aluminum- water explosion in a casthouse using an emerging CFD code – EXN-Aero by Envenio. Results for a typical casthouse are presented for use in the design of control rooms and other equipment.
