Abstract
The bursting sphere model is a simple approach to the numerical simulation of blast from charge detonation. It involves initializing a group of computational cells at high pressure with the correct blast energy to represent the charge volume. In this paper, a programme of numerical simulations of charge detonations in free-field air using the bursting sphere approach will be performed. This is done to investigate the errors in important blast parameters like peak overpressure and impulse that arise due to deviation of the charge shape from an ideal spherical profile when the charge is represented by a Cartesian mesh. This study will also include an assessment of the quality of error estimation for this problem based on grid refinement studies.
