This book was released on 2012-01-24 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high temperatures generated in gases by shock waves give rise to physical and chemical phenomena such as molecular vibrational excitation, dissociation, ionization, chemical reactions and inherently related radiation. In continuum regime, these processes start from the wave front, so that generally the gaseous media behind shock waves may be in a thermodynamic and chemical non-equilibrium state. This book presents the state of knowledge of these phenomena. Thus, the thermodynamic properties of high temperature gases, including the plasma state are described, as well as the kinetics of the various chemical phenomena cited above. Numerous results of measurement and computation of vibrational relaxation times, dissociation and reaction rate constants are given, and various ionization and radiative mechanisms and processes are presented. The coupling between these different phenomena is taken into account as well as their interaction with the flow-field. Particular points such as the case of rarefied flows and the inside of the shock wave itself are also examined. Examples of specific non-equilibrium flows are given, generally corresponding to those encountered during spatial missions or in shock tube experiments.

This book was released on 2007 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shock-tube experiments are typically performed at high temperatures ([greater than]1200K) due to test-time constraints. These test times are usually ~1 ms in duration and the source of this short, test-time constraint is loss of temperature due to heat transfer. At short test times, there is very little appreciable heat transfer between the hot gas and the cold walls of the shock tube and a high test temperature can be maintained. However, some experiments are using lower temperatures (approx. 800K) to achieve ignition and require much longer test times (up to 15 ms) to fully study the chemical kinetics and combustion chemistry of a reaction in a shock-tube experiment. Using mathematical models, analysis was performed studying the effects of temperature, pressure, shock-tube inner diameter, and test-port location at various test times (from 1-20 ms) on temperature maintenance. Three models, each more complex than the previous, were used to simulate test conditions in the endwall region behind the reflected shock wave with Ar and N2 as bath gases. Temperature profile, thermal BL thickness, and other parametric results are presented herein. It was observed that higher temperatures and lower pressures contributed to a thicker thermal boundary layer, as did shrinking inner diameter. Thus it was found that a test case such as 800K and 50 atm in a 16.2-cm-diameter shock tube in Argon maintained thermal integrity much better than other cases-- pronounced by a thermal boundary layer [less than]1 mm thick and an average temperature [greather than] 799.9 K from 1-20 ms.

This book was released on 1955 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nonlinear characteristic differential equations applicable to a quasi-one-dimensional unsteady channel flow with friction and heat transfer are linearized and integrated in functional form for the particular study of small perturbations from ideal shock-tube flows. If the equivalence of unsteady- and steady-flow boundary layers is assumed, the problem of determining the perturbation in the unsteady flow reduces to an evaluation of the drag of a flat plate in the equivalent steady flow.

This book was released on 1966 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of experimentally determining the transport properties of high temperature gases have been developed and measurements of viscosity, thermal conducitvity, and diffusion coefficients obtained. The heat transfer rate through laminar boundary layers, the absorption of sound, and a schlieren method have been investigated for the determination of transport properties. Heat transfer measurements on the side wall of the shock tube have been used to obtain viscosities of argon, oxygen, nitrogen, and carbon dioxide up to 4000 K. The boundary layer equations were solved for side wall boundary layers in the shock tube in oxygen to assess the relative importance of viscosity and thermal conductivity in heat transfer to the side wall. Thermal conductivities were deduced from end wall heat transfer measurements in carbon dioxide up to 2000 K and oxygen up to 4000 K. End wall heat transfer measurements in nitrogen and argon have been compared to theory with excellent agreement. Various methods for measuring ultrasonic absorption are discussed. The viscosity of argon at temperatures up to 8000 K were determined with the ultrasonic method. Diffusion coefficient in 50-50 He-Ar mixtures have also been obtained from the ultrasonic measurements at room temperature with excellent agreement with other investigators. The theory of a schlieren method for the measurement of thermal conductivity using the end wall boundary layer in the shock tube is discussed. (Author).
