Title Air Blast Calculations.
Publication Date Jul 2013
Media Count 24p
Personal Author J. B. Stewart
Abstract When an explosive detonates, the rapid expansion of reaction gases generates a shock wave that propagates into the surrounding medium. The pressure history at a given spatial location generally consists of an early positive (compressive) phase followed by a negative phase. This technical note documents a series of air blast calculations, using the Sandia hydrocode CTH, aimed at determining the pressure time histories at various gauge locations away from a spherical explosive charge suspended in air. A comparison of the results obtained using CTH are made to ones generated using the Friedlander approximation.
