Flame growth model for confined gas explosion

Large quantities of flammable gases are used in both commercial and residential applications. The risk associated with the use of these materials depends on an understanding of the impacts of an explosion, particularly the pressure‐time history during the explosion. This work provides a model to calculate the pressure‐time history for an explosion in a closed, spherical vessel. The model is expected to be of great benefit for characterizing these explosions and also for the design of explosion vents and other explosion protection systems.
