Eulerian Hydrocode Calculations of the Detonation of an Explosive Cylinder above a Water Surface

Abstract

A description is given of the current status of the Eulerian computations of a detonating cylinder above water. Calculations were made of pressure-time histories in the water resulting from the detonation of a one-pound cylinder of pentolite initially one foot above the surface. A two-dimensional Eulerian hydrodynamic code (CSQ) was used to obtain reflected pressures at the surface (considered rigid). These pressures were then used as input to a linear acoustic code for the propagation in the water. Pressure and impulse at various points in the water were calculated and compared with results from experiments. The Validity of the method is discussed, and possible checks and extensions are described.
