Book Description
Explosion generated surface waves in deep water is discussed. The tests will be carried out at pressures as low as 0.001 atmosphere in a large (10 ft diameter, 20 ft long) cylindrical vacuum vessel within which will be placed a rectangular tank (4 ft wide, 13 ft long, and 6 ft deep) filled to a depth of 5 ft with an inhibited transformer oil. The early events following detonations both above and below the fluid surface will be documented with high-speed motion picture photography. Four locations in the vertical will be examined with energy releases of from 1 to 300 calories. Both exploding wires and chemical explosives will be used as sources. Some preliminary tests with wires exploded in water at normal atmospheric pressure are described. (Author).

Book Description
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.

Book Description
The objectives of the study are: to develop a mathematical model appropriate for analysis of the behavior of surface effect vehicles (SEV) in unusually large waves; and subsequently to apply this model to investigate the vulnerability of these vehicles to explosion generated waves. The generation of surface waves due to an explosion is modeled mathematically as a function of the explosive yield, detonation depth and water depth. Further, the dynamic property of the propagated waves is treated to vary with the local water depth. The SEV dynamics are modeled mathematically by considering the vehicle as a rigid body having six degrees of freedom in space subject to an appropriate constraint derived from the cushion air dynamics as well as to the environmental excitations due to waves. Non-linear contributions including effects due to large motions, viscous flows, and control logics are considered and vehicle responses are solved numerically through time domain simulations. Analyses have been conducted using this analytical model to examine the potential threat of underwater explosions to a typical 2000-ton class SES, and the operational envelopes for such a vehicle in explosion generated wave environments are developed and discussed.

Book Description
The objective of this report is to combine all theoretical efforts to date and new theoretical developments under this contract into an effective method for predicting the surface water wave spectrum generated by surface or underwater explosions. Particular importance has been stressed on the data presentation in order to facilitate the use of this prediction method by those unfamiliar with the complicated analysis of the phenomena involved. The data is presented, in large, by graphical means and the user may obtain all pertinent information about the initial wave envelope by merely reading a series of graphs and performing some elementary multiplications. More detailed information about the actual waves present in the envelope may be obtained by some table searching and a minimal number of elementary multiplications. (Author).

Book Description
Excerpt from Water Waves Produced by Explosions In our analysis we assume that the surface elevation n and the accompanying water motion, are symmetric about an axis through the center of the disturbance. If r denotes distance from this axis and t denotes time then we may write n We also assume that the water is of finite uniform depth, which we denote by h and that the linear theory of surface waves is applicable. Both of these assumptions will be analysed in a later report. In the next two sections we present and discuss the results of our analyses for the cases of initial impulse and initial displacement respectively. Typical graphs of the wave height as a function of r and of t are included. Then in section IV these resulte are applied to the problem of wave production by explosions. The mathematical analysis is contained in an appendix. A list of references to previous work on this subject is appended. Of the previous work the earliest, that of Poisson is the most relevant. However he considers water of infinite depth. Furthermore he obtains detailed results only for paraboloidal and ellipsoidal depressions. Burnside [h] also considers infinite depth, but only twodimensional motion. He obtains a series for the wave motion produced by an initial elevation of very spe01al shape.

Book Description
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.
