Book Vibration and Dissociation Coupling Behind Strong Shock Waves

Download or read book Vibration and Dissociation Coupling Behind Strong Shock Waves written by Charles E. Treanor and published by . This book was released on 1962 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The coupling between vibrational relaxation and dissociation is discussed. A model for computations of dissociation behind strong shock waves is presented. It is shown that the loss of vibrational energy during dissociation introduces an inverse temperature dependence into the observed dissociation rate of O2 between 4000 and 8000K. Changing the model so that dissociation from higher vibrational levels is enhanced results in a dissociation-incubation time immediately behind the shock. The vibrational-energy distribution behind the shock is calculated, and shown to depart considerably from a Boltzmann distribution. The molecular model, which uses a Boltzmann distribution, is shown to give the same result as the non-Boltzmann model for both the nonequilibrium dissociation rate and the dissociation incubation time.

Book Method for Calculating Effects of Dissociation on Flow Variables in the Relaxation Zone Behind Normal Shock Waves

Download or read book Method for Calculating Effects of Dissociation on Flow Variables in the Relaxation Zone Behind Normal Shock Waves written by John S. Evans and published by . This book was released on 1956 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because the chemical reaction rates needed to predict the dependence of degree of dissociation on distance behind the shock are not known, order-of-magnitude estimates of their values have been used in a numerical example, the purpose of which is to illustrate the use of reaction-rate equations to predict relaxation time and distance behind the shock front.

Book Nonequilibrium Flow Behind Strong Shock Waves in a Dissociated Ambient

Download or read book Nonequilibrium Flow Behind Strong Shock Waves in a Dissociated Ambient written by G. R. Inger and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical study of effects of free stream dissociation on the nonequilibrium gas properties behind shock waves is described. The analysis is based on a set of oblique shock relations which are generalized to include an arbitrary degree of nonequilibrium vibration, dissociation or ionization ahead of and/or behind the shock front. The frozen and equilibrium post-shock gas properties in air vs the ambient atom mass fraction and dissociation energy are presented at shock velocites ranging from 15,000 to 30,000 fps for normal and oblique hypersonic shock waves. Some of the potential effects of predissociation on the intervening relaxation process are briefly examined. Comparison is made with the properties behind geometrically-similar shock waves in a perfect undissociated ambient gas, independently of the preshock chemical history, for either the same shock velocity or the same total enthalpy. Significant changes in the post-shock density ratio, temperature, dissociation and ionization can occur if 10% or more of the total energy is tied up in preshock dissociation. Sharp reductions in the usual differences between the frozen and equilibrium properties associated with endothermic post-shock relaxation are observed when 50% or more of the total enthalpy is in preshock dissociation.
