Available in PDF, EPUB and Kindle. Book excerpt: Generalized state-relationship correlations, giving the mass fractions of major gas species as functions of local fuel-equivalence ratios, were developed for hydrocarbon/air diffusion flames. Instantaneous soot volume fractions and temperatures were measured in the fuel-rich (underfire) region of turbulent nonpremixed acetylene, propylene, ethylene and propane flames burning in still air. The continuum radiation properties of the underfire region of luminous acetylene and propylene flames burning in still air were studied.

This book was released on 1987 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical and experimental study of the structure and radiation properties of turbulent buoyant diffusion flames is described. The results have application to modeling fires within structures, materials test methods, fire detection, and effects of materials on fire properties. The investigation consists of two phases, as follows: study of effects of turbulence/radiation interactions, considering the properties of nonluminous hydrogen/air diffusion flames; and study of extension of the laminar flamelet concept to soot properties needed to predict radiation from luminous acetylene/air and ethylene/air turbulent diffusion flames. Theory and experiment are considered in both phases of the investigation. Measurements in turbulent hydrogen/air diffusion flames yielded radiation fluctuation intensities of 20-110 percent, providing direct evidence of the importance of turbulence/radiation interactions. A stochastic analysis, based on the laminar flamelet concept, was developed which provided encouraging predictions of mean and fluctuating spectral radiation intensities (average discrepancies between predictions and measurements were roughly 30 percent), as well as temporal power spectral densities of radiation fluctuations. The temporal spectra exhibit energy-containing and inertial regions, very similar to other turbulence properties, although the rate of decay of the spectra with increasing frequency in the inertial region is somewhat greater than observed for scalar fluctuations. Measurements and predictions in the turbulent luminous flames concentrated on scalar properties (particularly soot volume fractions) in the overfire region. Predictions of scalar properties based on the laminar flamelet concept were very encouraging. Direct evaluation of soot volume fraction state relationships for the overfire region was hampered by effects of turbulent fluctuations and experimental uncertainties; nevertheless, within these limitations, soot volume fraction state relationships were nearly universal, and soot generation efficiencies nearly constant, for sufficiently long residence times. However, effects of finite-rate chemistry were noted for short residence time ethylene/air flames, causing spatial variations of soot generation efficiencies in the overfire region. For long residence times, present measurements of soot generation efficiencies were in reasonably good agreement with earlier findings for acetylene/air and ethylene/air diffusion flames.

Download or read book Radiative Heat Transfer in Turbulent Combustion Systems written by Michael F. Modest and published by Springer. This book was released on 2016-01-06 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: This introduction reviews why combustion and radiation are important, as well as the technical challenges posed by radiation. Emphasis is on interactions among turbulence, chemistry and radiation (turbulence-chemistry-radiation interactions – TCRI) in Reynolds-averaged and large-eddy simulations. Subsequent chapters cover: chemically reacting turbulent flows; radiation properties, Reynolds transport equation (RTE) solution methods, and TCRI; radiation effects in laminar flames; TCRI in turbulent flames; and high-pressure combustion systems. This Brief presents integrated approach that includes radiation at the outset, rather than as an afterthought. It stands as the most recent developments in physical modeling, numerical algorithms, and applications collected in one monograph.

This book was released on 1997-09-18 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reduction of the fire hazard of fuel is critical to improving survivability in impact-survivable aircraft accidents. Despite current fire prevention and mitigation approaches, fuel flammability can overwhelm post-crash fire scenarios. The Workshop on Aviation Fuels with Improved Fire Safety was held November 19-20, 1996 to review the current state of development, technological needs, and promising technology for the future development of aviation fuels that are most resistant to ignition during a crash. This book contains a summary of workshop discussions and 11 presented papers in the areas of fuel and additive technologies, aircraft fuel system requirements, and the characterization of fuel fires.
