Available in PDF, EPUB and Kindle. Book excerpt: When an explosion occurs in the atmosphere above a water surface, most of the energy in the resulting shock wave will be reflected upon striking the air-water interface; however, some portion of the energy will be transmitted through the interface and propagate into the water. The experimental study, designed to provide quantitative information on the induced water shock as well as verigy theoretical findings, was conducted in a trapezoidal-shaped test basin 250 ft long, 150 ft wide (midpoint), and 20 ft deep. It involved the detonation of some sixty 21-lb spheres of TNT positioned at various distances above the water surface, and pressure-time histories of the induced water shocks were measured at spatial positions underwater for depths ranging from just beneath the surface to middepth.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first book on explosion-generated water waves. It presents the theoretical foundations and experimental results of the generation and propagation of impulsively generated waves resulting from underwater explosions. Many of the theories and concepts presented herein are applicable to other types of water waves, in particular, tsunamis and waves generated by the fall of a meteorite. Linear and nonlinear theories, as well as experimental calibrations, are presented for cases of deep and shallow water explosions. Propagation of transient waves on dissipative, nonuniform bathymetries together with laboratory simulations are analyzed and discussed.

This book was released on 1975 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research has recently been conducted on the use of large buried chemical explosive charges for engineering excavation. Investigations in this area were initially concerned with crater formation in relatively homogeneous rock media, a process which is now well understood. However, it has become apparent that the greatest cost and operational advantages may be realized by applying the technique to rock excavation in an underwater environment. Cratering dynamics in an underwater (two-layer) configuration have not been well understood. Small-scale modeling tests and large-scale excavation projects have revealed two new factors which significantly influence underwater cratering processes: (1) early-time dynamic effects caused by the presence of the rock-water interface and water layer; and (2) very late-time water washback and slope failure effects in the crater vicinity. The report addresses the first of these two effects by means of hydrodynamic computer calculations.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The theory of oblique reflection of low amplitude exponential shock waves is considered in more detail than in preceding report (NavOrd 424) and is extended to include higher order reflections in shallow water. Errors arising from the use of the plane wave approximation are discussed. Recently published data on the attenuation of harmonic sound waves in sea water are used to develop a theory of the effect of viscous attenuation on the front of a shock wave propagating over long ranges. Crude correction is made for the compensating effects of finite amplitude. Experimental data on impulse and energy flux at long ranges are reported. The energy dissipation is analyzed in terms of the theory of viscous attenuation and attempt is made to account for the slope of the pressure-distance curve. Experimental data on negative gauge pressures in surface reflections are reported and analyzed in terms of a new treatment of the expected region of bulk cavitation. The data indicate a very low value of the “breaking tension: of sea water. An improved micro coulometer circuit for the calibration of piezoelectric gauges is described.

Download or read book Modeling Explosions and Blast Waves written by K. Ramamurthi and published by Springer Nature. This book was released on 2021-06-19 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: b="" The book provides a concise description of the physical processes and mathematical models for explosions and formation of blast waves from explosions. The contents focus on quantitatively determining the energy released in the different types of explosions and the destructive blast waves that are generated. The contribution of flames, detonations and other physical processes to the explosion phenomenon is dealt with in detail. Gaseous and condensed phase explosions are discussed and the yield of explosions with their TNT equivalence is determined. Time scales involved in the explosion process and the scaling procedure are ascertained. Explosions over the ground, in water, and the interaction of explosions with objects are examined. In order to keep the text easily readable, the detailed derivation of the mathematical equations is given in the seven appendices at the end of the book. Case studies of various explosions are investigated and simple problems and their solutions are provided for the different topics to assist the reader in internalizing the explosion process. The book is a useful reference for professionals and academics in aeronautics, mechanical, civil and chemical engineering and for personnel working in explosive manufacture and high-energy materials, armaments, space, defense, and industrial and fire safety.
