This book was released on 2018-07-11 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental observations of propane-air flames were performed. Measurements of hydroxyl (OH) radical concentration were made using resonance line absorption techniques. A microwave-pumped low pressure discharge in argon and water vapor is employed to produce strong OH radical band radiation in the 308 nm region. This radiation is transmitted through the plume and absorption data are taken at various radical positions using an optical multichannel analyzer. This absorption data is used to compute OH number density using a model for the absorption band characteristics as a function of temperature based on an atlas of line strengths. A numerical computation of flow fields, temperature profile and OH number density is carried out by using a technique of computational fluid dynamics (CFD). The results of CFD computation are good compared with experimental observation with a good agreement. Hung, R. J. Unspecified Center NAG8-102...

This book was released on 2012-07-30 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing concern about CO2 emissions and energy prices has led to new CO2 emission and fuel economy legislation being introduced in world regions served by the automotive industry. In response, automotive manufacturers and Tier-1 suppliers are developing a new generation of internal combustion (IC) engines with ultra-low emissions and high fuel efficiency. To further this development, a better understanding is needed of the combustion and pollutant formation processes in IC engines. As efficiency and emission abatement processes have reached points of diminishing returns, there is more of a need to make measurements inside the combustion chamber, where the combustion and pollutant formation processes take place. However, there is currently no good overview of how to make these measurements. Based on the author’s previous SAE book, Engine Combustion Instrumentation and Diagnostics, this book focuses on laser-based optical techniques for combustion flows and in-cylinder measurements. Included are new chapters on optical engines and optical equipment, case studies, and an updated description of each technique. The purpose of this book is to provide, in one publication, an introduction to experimental techniques that are best suited for in-cylinder engine combustion measurements. It provides sufficient details for readers to set up and apply these techniques to IC engines and combustion flows.

This book was released on 2020 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hydroxyl radical plays a critical role in several contexts including combustion, atmospheric chemistry, and low-temperature extraterrestrial environments. OH has been observed in the interstellar medium and is important in the gas phase chemistry of interstellar clouds. Additionally, the hydroxyl radical is the dominant oxidizer of volatile organic compounds in the atmosphere. Here, the reactions between OH and simple alkanes, alkenes, and alcohols were investigated as these bimolecular reactions can expand fundamental understanding of gas phase reaction dynamics. Photoelectron-photofragment coincidence (PPC) spectroscopy was used to characterize the energetics and dynamics of the OH + CH4 --> H2O + CH3 reaction initiated by photodetachment of the OH-(CH4) anion complex. PPC measurements at a photon energy of 3.20 eV yielded stable and dissociative channels. Interpretation of the experimental results was supported by quantum chemistry and quasiclassical trajectory calculations showing that most of the trajectories yield slowly recoiling OH + CH4 reactants while some are trapped in the entrance channel van der Waals well. Extending the study to hydroxy radical reactions with the simplest alkene, ethylene, yielded similar dissociative photodetachment dynamics (DPD) to PPC studies on OH-(CH4). The dominant channel was DPD to OH + C2H4 + e- with a low kinetic energy release (KER) of the dissociating fragments, consistent with weak repulsion between the OH + C2H4 reactants near the transition state. To model the DPD process, an impulsive model was used to account for rotational energy partitioning in C2H4 photofragments and showed good agreement with the experimental results. PPC studies probing the OH + CH3OH --> H2O + CH3O reaction had the best Franck-Condon overlap with the exit channel. High-level coupled cluster calculations of the stationary points on the anion surface show that CH3O-(H2O) is the stable minimum. Photodetachment leads to H2O + CH3O + e- products with both direct dissociative photodetachment as well as resonance mediated processes observed on the neutral surface. The partitioning of total kinetic energy in the system indicates that water stretch and bend excitation is induced in DPD, and evidence for long-lived complexes consistent with production of vibrational Feshbach resonances in the exit channel is reported.
