Book Description
A Gallery of Combustion and Fire is the first book to provide a graphical perspective of the extremely visual phenomenon of combustion in full color. It is designed primarily to be used in parallel with, and supplement existing combustion textbooks that are usually in black and white, making it a challenge to visualize such a graphic phenomenon. Each image includes a description of how it was generated, which is detailed enough for the expert but simple enough for the novice. Processes range from small scale academic flames up to full scale industrial flames under a wide range of conditions such as low and normal gravity, atmospheric to high pressures, actual and simulated flames, and controlled and uncontrolled flames. Containing over 500 color images, with over 230 contributors from over 75 organizations, this volume is a valuable asset for experts and novices alike.

Book Description
This book provides an introduction to understanding combustion, the burning of a substance that produces heat and often light, in microgravity environments-i.e., environments with very low gravity such as outer space. Readers are presented with a compilation of worldwide findings from fifteen years of research and experimental tests in various low-gravity environments, including drop towers, aircraft, and space.Microgravity Combustion is unique in that no other book reviews low- gravity combustion research in such a comprehensive manner. It provides an excellent introduction for those researching in the fields of combustion, aerospace, and fluid and thermal sciences. * An introduction to the progress made in understanding combustion in a microgravity environment* Experimental, theoretical and computational findings of current combustion research* Tutorial concepts, such as scaling analysis* Worldwide microgravity research findings

Book Description
Understanding the spontaneous ignition and burning behavior of liquid fuels is critical to improving the performance of modern combustion devices. This work examines the effects of varying ambient temperature and pressure on the autoignition and burning characteristics of fiber-supported n-dodecane fuel droplets in normal gravity and in microgravity. Ambient temperatures and pressures were 500 to 1000 K and 1 to 25 atm, respectively, encompassing the transcritical region for n-dodecane. The results show the dynamics of ignition with the formation of a cool-flame front and a hot-flame front prior to the final establishment of a diffusion flame surrounding the droplet. These phenomena are observed for both normal gravity and microgravity environments. Measurement of two-stage ignition delay times shows qualitative agreement with previous research.

Book Description
A new numerical model for the simulation of liquid fuel droplet vaporization and combustion time-histories under conditions of no body forces or bulk fluid flow is developed. Assuming spherosymmetry, the model applies finite volume methods combined with high-order implicit time integration to the system of interest. Molecular transport, thermal radiation, thermophysical properties, and chemical kinetic behaviors are represented in rigorous detail. Specifically, this effort represents the first implementation of a Stefan-Maxwellian transport formulation and of a spectrally-resolved radiant thermal transport formulation to this physical configuration. Particular effort has been applied toward computational efficiency so that the interactive complexities of these phenomena can be represented with substantial detail. Liquid fuels, consisting of n-heptane, n-nonane, n-hexadecane and methanol, under a variety of ambient conditions were simulated yielding generally good agreement with experiment and highlighting areas for future model development where discrepancies do exist. In particular, the highly modular design allows for the inclusion and comparison of differing chemical, thermodynamic and transport representations, aiding in the validation of simplified representations, highlighting the impact of more detailed ones and making the inclusion of new phenomena such as soot production or radiative penetration of the liquid phase dependent only on developing the appropriate submodel.
