Book Description
A general description is given of the Pre-Buggy chemical explosive experiments. These experiments consisted of a series of single- and multiple- charge detonations designed to refine our knowledge of channel size as a function of charge spacing, and to obtain data on venting of explosion products from a row of spherical charges detonated in alluvium. A basic series of six single-charge detonations and four multiple-charge detonations of five charges in a row was executed in Area 5 of the Nevada Test Site from November 1982 through February 1983. Each charge contained 1,000 pounds of nitromethane with a La14° tracer. Preliminary examination of the results indicates that: (1) When charges were spaced at 1.0 single-charge crater radius, the channel depth and width were larger than the diameter and depth of a single-charge crater. (2) Small increases in spacing resulted in considerable reduction of channel depth and a smaller reduction in width. (3) The channel shape at spacings of 1.5 single- charge crater radii was very uneven. (4) When the ratio of the depth-of-burst to depth-of-crater was about two, the venting of explosion products from a row- charge detonation was less than from single-charge detonations. (auth).

Water Waves Produced by Cratering Explosions in Shallow Water
Author: W. J. Garcia
Publisher:
ISBN:
Category : Nuclear excavation
Languages : en
Pages : 16
Book Description
In the course of developing the capability of predicting the characteristics of water waves generated by explosions detonated in shallow water beneath the ocean floor, the pertinent data from past experiments were analysed using dimensional analysis as a framework. Data were examined from one series of high explosive cratering experiments detonated beneath the floor in shallow water, and from two series of high explosive experiments and one nuclear explosive experiment detonated above the floor in shallow water. The data indicate that the maximum radius of the water column produced by the explosion is proportional to the cube root of the ratio of explosive yield to ambient pressure at the point of detonation. Further, the data show that the maximum radius of the column of water is proportional to the square root of the product of wave height and distance from the source. The conclusions of this scheme of analysis are being tested with hydrodynamic computer code calculations.

Scaling Dimensions of Craters Produced by Buried Explosions
Author: Albert J. Chabai
Publisher:
ISBN:
Category : Cratering
Languages : en
Pages : 56
Book Description
The question of the proper scaling of crater dimensions resulting from buried explosions is investigated. Dimensional analyses are performed from which four different scaling rules are derived. Data are reviewed in an attempt to distinguish which scaling rules are fundamental to cratering. Inability to perform cratering experiments with similitude apparently is one reason for lack of an unambiguous answer to the scaling question. Influences of possible sources of similarity violation are qualitatively examined, and some experiments are suggested which may provide more direct information about the correct scaling of crater dimensions.
