Download or read book Ignition and Wave Processes in Combustion of Solids written by Nickolai M. Rubtsov and published by Springer. This book was released on 2017-04-22 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the application of classical combustion theory to ignition and flame propagation in solid-solid and gas-solid systems. It presents experimental investigations in the areas of local ignition, filtration combustion, self-propagating high temperature synthesis and nanopowders protection. The authors highlight analytical formulas used in different areas of combustion in solids and propose an approach based on classical combustion theory. The book attempts to analyze the basic approaches to understanding of solid-solid and solid - gas combustion presented in contemporary literature in a unified approach based on classical combustion theory.

Book excerpt: A theory of ignition is presented to analyze the effect of porosity on the time to ignition of a semi-infinite porous energetic solid subjected to a constant energy flux. An asymptotic perturbation analysis, based on the smallness of the gas-to-solid density ratio and the largeness of the activation energy, is utilized to describe the inert and transition stages leading to thermal runaway. As in the classical study of a nonporous solid, the transition stage consists of three spatial regions in the limit of large activation energy: a thin reactive-diffusive layer adjacent to the exposed surface of the material where chemical effects are first felt, a somewhat thicker transient-diffusive zone, and finally an inert region where the temperature field is still governed solely by conductive heat transfer. Solutions in each region are constructed at each order with respect to the density-ratio parameter and matched to one another using asymptotic matching principles. It is found that the effects of porosity provide a leading-order reduction in the time to ignition relative to that for the nonporous problem, arising from the reduced amount of solid material that must be heated and the difference in thermal conductivities of the solid and gaseous phases. A positive correction to the leading-order ignition-delay time, however, is provided by the convective flow of gas out of the solid, which stems from the effects of thermal expansion and removes energy from the system. The latter phenomenon is absent from the corresponding calculation for the nonporous problem and produces a number of modifications at the next order in the analysis arising from the relative transport effects associated with the gas flow.
Download or read book Ignition of Solids written by Vladimir Nikiforovich Vili︠u︡nov and published by Elsevier Publishing Company. This book was released on 1989 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ignition of condensed substances is a recent scientific trend in combustion and explosion physics. Its principal results have been obtained largely by using computers and modern experimental techniques. In this book the authors present a comprehensive theoretical examination of various ignition models and the elaboration of experimental approaches for their description. The first three chapters were originally published in 1984 in Russian (V.N. Vilyunov, Ignition Theory of Condensed Substance, Nauka, Novosibirsk). For this English edition they have been revised and supplemented by new material. Two completely new chapters have also been added: one devoted to experimental studies and the other to local ignition problems. The book is the result of several years of active experience in the field of ignition. It will be of particular interest to research workers in chemical physics and to engineers dealing with the problems of fire-explosion accident prevention.

This book was released on 2012-12-06 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Besides its obvious destructive potential, military R&D also serves to protect human lives, equipment and facilities against the effects of weapons. Concepts have therefore been developed that improve safety of stationary and mobile facilities against pressure waves, thermal radiation and fire. Effective, fast fire extinguishing equipment has been designed for tank compartments and motors. Closed buildings are demolished and landmines are removed with gas and dust explosions. Stringent safety requirements have been developed for the production of ammunition and explosives. Military and related industries have accumulated a vast knowledge and sophisticated experience that are very valuable in a variety of civil applications. The knowledge is based on theoretical and experimental research work, the origin of which sometimes dates back many centuries. It has often been classified and therefore has remained unknown to the civilian population, until now.

Available in PDF, EPUB and Kindle. Book excerpt: A continuation of an ignition analysis for porous energetic materials subjected to a constant energy flux is presented. In the first part (I), the analysis was developed for the case of an open-end, semi-infinite material such that gas flow, generated by thermal expansion, flowed out of the porous solid, thereby removing energy from the system. In the present study, the case of a closed end is considered, and thus the thermally-induced gas flow is now directed into the solid. In these studies, an asymptotic perturbation analysis, based on the smallness of the gas-to-solid density ratio and the largeness of the activation energy, is utilized to describe the inert and transition stages leading to thermal runaway. In both cases it is found that the effects of porosity provide a leading-order reduction in the time to ignition relative to that for the nonporous problem, arising from the reduced amount of solid material that must be heated and the difference in thermal conductivities of the solid and gaseous phases. A correction to the leading-order ignition-delay time, however, is provided by the convective flow of gas through the solid, and the sign of this correction is shown to depend on the direction of the gas flow. Thus, gas flowing out of an open-end solid was previously shown to give a positive correction to the leading-order time to ignition. Here, however, it is demonstrated that when the flow of gas is directed into the porous solid, the relative transport effects associated with the gas flow serve to preheat the material, resulting in a negative correction and hence a decrease in the ignition-delay time.
