Book Description
This book provides an analysis of contemporary problems in combustion science, namely flame propagation, detonation and heterophaseous combustion based on the works of the author. The current problems in the area of gas combustion, as well as the methods allowing to calculate and estimate limiting conditions of ignition, and flame propagation on the basis of experimental results are considered. The book focuses on the virtually inaccessible works of Russian authors and will be useful for experienced students and qualified scientists in the area of experimental studies of combustion processes.

Book Description
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 Description
A theoretical and experimental investigation of the oxidation of molybdenum to molybdenum trioxide at temperatures at which the trioxide is volatile has been carried out. A rate equation has been derived which includes the effects of mass-transfer parameters as well chemical parameters and is applicable to any situation for which a mass-transfer coefficient can be obtained. The derived equation has been applied to previously reported rate data taken under laboratory conditions using air and oxygen-helium mix-reported rate data taken under laboratory conditions using air and oxygen-helium mixtures flowing at low subsonic velocities, and a set of values for the activation energy of the oxidation of molybdenum has been obtained. The average of these values is 8.51 x 107 J-(kg-mole)−1 (20.3 kcal-(g-mole)−1) with a standard deviation of 2.1 percent. In addition, 32 molybdenum hemisphere-cylinder specimens have been oxidized in a Mach 2.1 heated airstream at a free-stream stagnation pressure of 1.07 x 106 N-m-−2 (10.5 atm) and free-stream stagnation temperatures from 1765°K to 2120°K. The stagnation-point surface temperature and recession rate were determined for each of the specimens. The observed recession rates were compared with the corresponding values predicted theoretically by the derived rate equation and agreement within a factor of about 2 was obtained for most specimens. However, a few specimens ignited, exhibiting recession rates much greater than those predicted theoretically. The high recession rates associated with ignition were found to be the result of a sharp rise in surface temperature which caused some melting of the specimens in addition to their normal oxidation.

Book Description
This thesis presents pioneering experimental and numerical studies on three aspects of the combustion characteristics of lean premixed syngas/air flames, namely the laminar flame speed, extinction limit and flammability limit. It illustrates a new extinction exponent concept, which enriches the combustion theory. Above all, the book provides the following: a) a series of carefully measured data and theoretical analyses to reveal the intrinsic mechanisms of the fuel composition effect on the propagation and extinction of lean syngas/air flames; b) a mixing model and correlation to predict the laminar flame speed of multi-component syngas fuels, intended for engineering computations; c) a new “extinction exponent” concept to describe the critical effects of chemical kinetics on the extinction of lean premixed syngas/air flames; and d) the effects and mechanism of the dilution of incombustible components on lean premixed syngas/air flames and the preferential importance among the thermal, chemical and diffusion effects.
