This book was released on 1992 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The converging-diverging nozzle geometries, which are presently proposed for hypersonic propulsion systems, are characterized by large expansion area ratios, and by a geometrically variable nozzle throat to control the engine mass flow. Within the expanding nozzle flow, chemical recombination reactions of the combustor exhaust gas products will occur; the limited chemical reaction rates generally leading to a relaxation of the chemical species composition.

This book was released on 1969 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new technique is presented for the numerical solution of quasi-one-dimensional, vibrational and chemical nonequilibrium nozzle flows including nonequilibrium conditions both upstream and downstream of the throat. This new technique is a time-dependent analysis which entails the explicite finite-difference solution of the quasi-one-dimensional unsteady flow equations in steps of time, starting with assumed initial distributions throughout the nozzle. The steady-state solution is approached at large values of time. A virtue of the present time-dependent analysis is its simplicity, which prevails from its initial physical formulation to the successful receipt of numerical results. Also, the present solution yields the transient as well as the steady-state nonequilibrium nozzle flows. To exemplify the present analysis, results are given for several cases of vibrational and chemical nonequilibrium expansions through nozzles. (Author).

This book was released on 1962 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work described is a continuation of that reported previously in AEDC-TN-61-65 (calculation of the one-dimensional nonequilibrium flow of air through a hypersonic nozzle). In particular, a method is presented for the exact numerical calculation of the one-dimensional nonequilibrium flow of a general gas mixture through a converging-diverging nozzle. General equations are given for a mixture of perfect gases with an arbitrary number of species undergoing an arbitrary number of chemical and vibrational rate processes. An inexact but accurate method, similar in form to the method employed in the nonequilibrium case, is also given for calculating the corresponding one-dimensional equilibrium flow. The numerical method of solution applicable to both cases is described, including a simple procedure for starting the nonequilibrium calculations from an equilibrium condition and an improved method for controlling integration step size. The factors that affect over-all computation time are discussed. A computer program for an IBM 7090 has been written for the general gas mixture. Specific calculations are reported for a model of air consisting of O, N, NO, N2, and O2 and including eight chemical reactions plus the vibrational processes of the three diatomic species.

This book was released on 1963 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical and vibrational nonequilibrium phenomena in steady inviscid flow fields are studied by the analysis of flow past curved boundaries. Possible alternative choices of the state variables to be used are considered. General features of the nonequilibrium flow are studied by examination of the mathematical properties of the nonlinear flow equations. An axisymmetric nonequilibrium flow of air through a supersonic nozzle is analyzed by means of numerical computations. The coupling effects between nonuniformity (across a nozzle section) and nonequilibrium, not taken into account in the quasi-one-dimensional flow approximation, are revealed by the present analysis.

Book excerpt: The feasibility of performing accurate calculations on the non-equilibrium flow of a complicated gas mixture through nozzles, with particular reference to the propulsive nozzle of the hypersonic ram-jet is studied. Equations are given for the steady, quasi-one-dimensional, adiabatic flow of a gener l reacting gas mixture, consisting of N species related through N chemical reactions. A number of alternative methods of obtaining numerical solutions are evaluated. The formulation of the system of chemical reactions is also discussed, together with the availability of the large amount of thermo ynamic and chemical kinetic data which is required before a numeric l solution can be attempted. It is found that the most serious difficulty to be overcome before accurate non-equilibrium nozzle calculations can be performed, is obtaining reliable data on the rates of the many chemical reactions which may be involve .
