Available in PDF, EPUB and Kindle. Book excerpt: This work describes an approximate solution to the problem of an intense point-source explosion at the interface separating two different fluids; in particular, it is applied to a nuclear explosion initiated on the surface of the ocean. Of special interest is the position of the deformed ocean surface as a function of time during the initial phase of the explosion. The gasdynamic equations of motion for an inviscid fluid with no heat conductivity are written in terms of the vertical angle. The formulation of the governing equations in terms of this similarity variable is possible because only two parameters of independent dimensions enter the problem; that is, the charge energy and the density of the medium into which the blast propagates. The present solution is valid for the early phase of the explosion, during which the counterpressure remains insignificant. A maximum shock radius maybe computed, up to which the explosion remains sufficiently intense to satisfy this condition. It is found that the influence of the free surface on the vacuum interface propagated in the water is confined to a 45 degree sector adjacent to the original free surface. Below this, the vacuum surface retains very nearly its spherical form. This picture of the flow field form is seen to be in good qualitative agreement with the type of flow fields calculated by Brode and Bjork for a megaton burst on the surface of the earth. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The problem of a point explosion detonated at the interface between two different media, for example, at the ocean surface, is formulated. It is proposed to solve the problem by considering a linear perturbation of the similarity solutions developed for a point explosion in the spherically symmetric case. (Author).

This book was released on 1970 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current knowledge of the physical effects of underwater explosions on the environment is summarized, with particular attention to the heating of water, the mixing of explosion products with water, and cratering. Theory and data indicate that thermal effects on the environment are negligible because rapid turbulent mixing reduces any temperature excess to a negligible amount within minutes. Virtually no data are available on the mixing of explosion products with water and air. However, information on the bubble and surface phenomena of underwater explosions has been utilized to provide qualitative guidance concerning the distributions immediately after a test. Existing theories of turbulent diffusion can be applied to calculate the subsequent history of the products. Knowledge of the physical effects of bottom explosions on the environment is limited to crater measurements in shallow water and some data on the behavior of explosion bubbles in deep water. Suggested programs to fill gaps in current knowledge are outlined. (Author).

Download or read book Optical Remote Sensing of Ocean Hydrodynamics written by Victor Raizer and published by CRC Press. This book was released on 2019-03-04 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Remote Sensing is one of the main technologies used in sea surface monitoring. Optical Remote Sensing of Ocean Hydrodynamics investigates and demonstrates capabilities of optical remote sensing technology for enhanced observations and detection of ocean environments. It provides extensive knowledge of physical principles and capabilities of optical observations of the oceans at high spatial resolution, 1-4m, and on the observations of surface wave hydrodynamic processes. It also describes the implementation of spectral-statistical and fusion algorithms for analyses of multispectral optical databases and establishes physics-based criteria for detection of complex wave phenomena and hydrodynamic disturbances including assessment and management of optical databases. This book explains the physical principles of high-resolution optical imagery of the ocean surface, discusses for the first time the capabilities of observing hydrodynamic processes and events, and emphasizes the integration of optical measurements and enhanced data analysis. It also covers both the assessment and the interpretation of dynamic multispectral optical databases and includes applications for advanced studies and nonacoustic detection. This book is an invaluable resource for researches, industry professionals, engineers, and students working on cross-disciplinary problems in ocean hydrodynamics, optical remote sensing of the ocean and sea surface remote sensing. Readers in the fields of geosciences and remote sensing, applied physics, oceanography, satellite observation technology, and optical engineering will learn the theory and practice of optical interactions with the ocean.

Download or read book Energy Partition in Point Source Explosions at the Ocean Surface and Ocean Bottom written by M. Holt and published by . This book was released on 1968 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates are made of the partition of energy when a point source explosion is iniated either at the surface or bottom of the ocean. A distinction is made between radiation energy and blast energy. The partition of purely radiant energy, neglecting blast wave effects, is easily calculated. The partition of blast energy at the ocean bottom can be found without taking account of radiation but the corresponding partition at the ocean surface is changed completely when radiation effects are included.

Available in PDF, EPUB and Kindle. Book excerpt: What happens at the end of the life of massive stars? At one time we thought all these stars followed similar evolutionary paths. However, new discoveries have shown that things are not quite that simple. This book focuses on the extreme –the most intense, brilliant and peculiar– of astronomical explosions. It features highly significant observational finds that push the frontiers of astronomy and astrophysics, particularly as before these objects were only predicted in theory. This book is for those who want the latest information and ideas about the most dramatic and unusual explosions detected by current supernova searches. It examines and explains cataclysmic and unusual events in stellar astrophysics and presents them in a non-mathematical but highly detailed way that non-professionals can understand and enjoy.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines the reasons behind the resonant amplification of seismic and ocean waves that have the capacity to destroy cities and ocean-going vessels. Using Charles Darwin’s important geophysical research as a starting point, it provides insights into the interaction between earthquakes with volcanoes, seaquake, and tsunami formation. In particular, the author details the observations that Darwin made on a powerful earthquake that occurred in Chile in 1835, noting how the famous naturalist and geologist used the concept of earthquake-induced vertical shock to explain the event's devastating impact. The book then goes on to show how Darwin's concept relates to the catastrophic results of the shallow quakes that recently destroyed Port-au-Prince (Haiti, 2010) and severely damaged Christchurch (New Zealand, 2011). In addition, the author asks whether Darwin's ideas are endorsed by the discoveries of modern science and whether the results of destructive earthquakes can be modeled using strongly nonlinear wave equations. Coverage also proposes that similar equations can be used to simulate the dynamics of many objects on the surface of the Earth, and to model the origin of the Universe, dark matter, and dark energy as strongly nonlinear wave phenomena. The book will appeal to students as well as researchers and engineers in geophysics, seismology, nonlinear wave studies, cosmology, physical oceanography, and ocean and coastal engineering. It will also be of use to those who are interested in the phenomena of natural catastrophes as well as those who want to learn more about the life and work of Charles Darwin.
