Abstract
This Technical Note describes the development of an Excel-based interface that provides the physical properties of blast waves generated by centred propane explosions. The user can input the mass or volume of propane and the ambient atmospheric pressure and temperature. The physical properties output by the interface can be displayed as the peak values immediately behind the incident shock as functions of distance, as time histories at selected radii, and as wave profiles at selected times after detonation. The results are based on analyses of the measurements of the blast wave produced by a 20-ton TNT equivalent explosion of a surface-burst hemispherical stoichiometric propane/oxygen mixture. The outputs from the interface were evaluated by comparing them with measurements of the blast waves generated by a series of 644-mg stoichiometric propane/oxygen explosions carried out by I. Sochet at INSA, Bourges, France. An example is given to illustrate how the interface can be used to analyse the properties of blast waves generated by propane/oxygen explosions. Instructions are provided as to how the interface and associated users’ guide can be downloaded.
