THE INITIAL GROWTH OF A SPHERICAL EXPLOSION IN SEA WATER

Abstract

This report describes the first stages of the calculation of the growth of a spherical explosion in sea water, due to a charge of PETN initiated at its center. Working in the time distance plane, the analysis of Holt (1955 and 1956) is used to construct a "plus" characteristic traversing the whole field of disturbance near the origin of blast and the "minus" characteristic which is the outer boundary of the detonation region. These initial data are then used to start a calculation of the further growth of the blast field by the numerical method of characteristics. This is programmed on an IBM CPC computer. A procedure is established which is satisfactory in principle but unsuitable for repeated application on this particular computer owing to inadequate storage facilities. As a consequence only the first stages of the calculation are carried out now and the work will be completed later on an IBM 70+ computer.
