Bubble Dynamics Calculations Using the DYSMAS/E Finite Difference Code

Abstract

A method of calculating underwater bubble collapse using the DYSMAS/E code is presented. The effects on bubble growth and collapse of a nearby rigid boundary and the free surface are included in the analysis. The solution methodology is described, and the advantages and disadvantages of compressible flow theory are compared to incompressible flow theory. The approach is shown to give reasonable results in comparison to observed explosion bubble behavior. This report also contains a preliminary look at the formation of a bubble jet.
