Book Handbook of Shock Waves Three Volume Set

Download or read book Handbook of Shock Waves Three Volume Set written by Gabi Ben-Dor and published by Elsevier. This book was released on 2000-10-18 with total page 2188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Shock Waves contains a comprehensive, structured coverage of research topics related to shock wave phenomena including shock waves in gases, liquids, solids, and space. Shock waves represent an extremely important physical phenomena which appears to be of special practical importance in three major fields: compressible flow (aerodynamics), materials science, and astrophysics. Shock waves comprise a phenomenon that occurs when pressure builds to force a reaction, i.e. sonic boom that occurs when a jet breaks the speed of sound.This Handbook contains experimental, theoretical, and numerical results which never before appeared under one cover; the first handbook of its kind.The Handbook of Shock Waves is intended for researchers and engineers active in shock wave related fields. Additionally, R&D establishments, applied science & research laboratories and scientific and engineering libraries both in universities and government institutions. As well as, undergraduate and graduate students in fluid mechanics, gas dynamics, and physics. Key Features* Ben-Dor is known as one of the founders of the field of shock waves* Covers a broad spectrum of shock wave research topics* Provides a comprehensive description of various shock wave related subjects* First handbook ever to include under one separate cover: experimental, theoretical, and numerical results

Book High Temperature Kinetic Study of the Reactions H O2 Oh O and O H2 Oh H in H2 O2 System by Shock Tube Laser Absorption Spectroscopy

Download or read book High Temperature Kinetic Study of the Reactions H O2 Oh O and O H2 Oh H in H2 O2 System by Shock Tube Laser Absorption Spectroscopy written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-17 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reactions: (1) H + O2 = OH + O; and (2) O + H2 = OH + H are the most important elementary reactions in gas phase combustion. They are the main chain-branching reaction in the oxidation of H2 and hydrocarbon fuels. In this study, rate coefficients of the reactions and have been measured over a wide range of composition, pressure, density and temperature behind the reflected shock waves. The experiments were performed using the shock tube - laser absorption spectroscopic technique to monitor OH radicals formed in the shock-heated H2/O2/Ar mixtures. The OH radicals were detected using the P(1)(5) line of (0,0) band of the A(exp 2) Sigma(+) from X(exp 2) Pi transition of OH at 310.023 nm (air). The data were analyzed with the aid of computer modeling. In the experiments great care was exercised to obtain high time resolution, linearity and signal-to-noise. The results are well represented by the Arrhenius expressions. The rate coefficient expression for reaction (1) obtained in this study is k(1) = (7.13 +/- 0.31) x 10(exp 13) exp(-6957+/- 30 K/T) cu cm/mol/s (1050 K less than or equal to T less than or equal to 2500 K) and a consensus expression for k(1) from a critical review of the most recent evaluations of k(1) (including our own) is k(1) = 7.82 x 10(exp 13) exp(-7105 K/T) cu cm/mol/s (960 K less than or equal to T less than or equal to 5300 K). The rate coefficient expression of k(2) is given by k(2) = (1.88 +/- 0.07) x 10(exp 14) exp(-6897 +/- 53 K/T) cu cm/mol/s (1424 K less than or equal to T less than or equal to 2427 K). For k(1), the temperature dependent A-factor and the correlation between the values of k(1) and the inverse reactant densities were not found. In the temperature range of this study, non-Arrhenius expression of k(2) which shows the upward curvature was not supported. Ryu, Si-Ok and Hwang, Soon Muk and Dewitt, Kenneth J.

Book A Shock Tube Study of the H2 O2 CO Ar and H2 N2O CO Ar Systems

Download or read book A Shock Tube Study of the H2 O2 CO Ar and H2 N2O CO Ar Systems written by Anthony M. Dean and published by . This book was released on 1977 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emissions at 450 nm and 4.27 micrometers have been measured when a variety of mixtures containing H2, CO, either O2 or N2O, and Ar were heated behind reflected shock waves to temperatures of 2000-2850 K and total concentrations near 5 x 10 to the 18th power molecule/cc. These emissions were used to obtain absolute concentration - time data for both oxygen atoms and carbon dioxide. The data were then compared to the results of numerical integrations of the likely mechanisms. It was observed that quantitative agreement between calculations and observations were obtained for the H2/CO/O2/Ar system using recent high temperature literature rate constants. For the H2/CO/N2O/Ar system, the rate constant for the reaction: H + N2O yields N2 + OH was adjusted so as to fit the data. Here it was found that a good fit to both (O) and (CO2) profiles could be achieved with k = 3 x 10 to the -9th power exp( -113kJ/RT) cc/molecule. Comparison to data at lower temperatures suggests that this might be another example of a 'Non-Arrhenius' rate constant. The implications of these results to studies of hydrocarbon oxidation are discussed. (Author).

Book Ignition Delay Times and Structure of Detonation Waves in CH4 O2 N2 and H2 O2 N2 Mixtures

Download or read book Ignition Delay Times and Structure of Detonation Waves in CH4 O2 N2 and H2 O2 N2 Mixtures written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simplified chemical-kinetic mechanisms and reduced chemical-kinetic mechanisms were developed for describing structure of the dark zone formed over the burning surface of double base and nitramine propellants. It is believed that ignition delays in large caliber gun ballistic cycles are related to the chemistry taking place in the dark zone. Ignition delay times calculated using the simplified mechanisms were found to agree well with those calculated using detailed chemical-kinetic mechanisms. The simplified mechanisms are expected to be useful in interior ballistics calculations. Reduced chemical-kinetic mechanisms were developed to calculate the structures of premixed and nonpremixed flames burning various hydrocarbon fields. Asymptotic analyses were performed using the reduced mechanisms. Burning velocities of premixed flames and critical conditions of extinction of nonpremixed flames were calculated using results of the asymptotic analyses. Simplified chemical-kinetic mechanisms were developed for calculating ignition delay times in combustible mixtures used in the Ram Accelerator. The results of all these studies are described in eight journal articles and five technical reports published in proceedings of technical meetings.
