Numerical Methods for Explosion Plume Predictions
Abstract
A computational study has been conducted of the plume created by an underwater explosion. Calculations have been performed with a compressible and an incompressible method. The later method was found to be more economical in treating the relatively long-term phenomena associated with the explosion plume, which takes several seconds to form and decay. Both techniques suggest that the formation of an explosion plume can be divided into five different phases: cavity formation, cavity collapse, venting, jetting, and rebound. Unfortunately, the internal plume structure predicted by calculation cannot be verified at this time due to the absence of experimental data describing the density distribution within the plume.
