This article provides an overview showing the value of CFD for the study of explosions. Although computational fluid dynamics finds a great deal of use in solving very complex problems, its value is not limited to complex problems. Many relatively simple problems can be solved quickly and economically with the use of CFD. The intent of this article is to show industry the possibilities that exist for improving safety when the physics of explosions are better understood.
