Chemical reactions in turbulent mixing flows by Paul E Dimotakis( Book )

15 editions published between 1986 and 1993 in English and held by 15 WorldCat member libraries worldwide

Work continues primarily in gas phase turbulent mixing amd chemical reactions with extensions to compressible (supersonic) shear layers. In the gas phase shear layer work, investigations concentrate on subsonic shear layer free stream density ratio effects, and a design effort in support of the planned extension of the hydrogen-fluorine shear flow facility to supersonic flows. In jet flows, measurements of gas phase jet mixing, using laser Rayleigh scattering techniques developed for conserved scalar measurements down to diffusion space and time scales, are in progress. A first publication has just appeared on an experiment in which digital imaging of soot in turbulent flames was used to describe combustion flame sheets in methane flames. Analytical/computational modeling efforts included development of quantitative description of turbulent jet mixing and chemical reactions including finite Damkoehler number effects; supersonic shear layer combustion studies of finite kinetic rate (Damkoehler number) effects for H2/F2/NO and H2/air systems; a new analytical model for turbulent shear layer mixing and chemical reactions; and extensions of hydrodynamic stability calculations to include Mach number effects in supersonic shear layers
The coherent flame model for turbulent chemical reactions by Frank E Marble( Book )

3 editions published between 1977 and 1982 in English and held by 5 WorldCat member libraries worldwide

A description of the turbulent diffusion flame is proposed in which the flame structure is composed of a distribution of laminar diffusion flame elements, whose thickness is small in comparison with the large eddies. These elements retain their identity during the flame development; they are strained in their own plane by the gas motion, a process that not only extends their surface area, but also establishes the rate at which a flame element consumes the reactants. Where this flame stretching process has produced a high flame surface density, the flame area per unit volume, adjacent flame elements may consume the intervening reactant, thereby annihilating both flame segments. This is the flame shortening mechanism which, in balance with the flame stretching process, establishes the local level of the flame density. The consumption rate of reactant is then given simply by the product of the local flame density and the reactang consumption rate per unit area of flame surface. The proposed description permits a rather complete separation of the turbulent flow structure, on one hand, and the flame structure, on the other, and in this manner permits the treatment of reactions with complex chemistry with a minimum of added labor. The structure of the strained laminar diffusion flame may be determined by analysis, numerical computation, and by experiment without significant change to the model

An analysis of the fluid mechanics of secondary injection for thrust vector control (revised)( Book )

1 edition published in 1962 in English and held by 2 WorldCat member libraries worldwide

An analysis is made of the interaction of an injected gas or liquid with a supersonic stream AND THE FORCE INDUCED ON AN ADJACENT WALL PREDICTED. The study deals only with the free stream-injectant interaction; the modifications to the flow intro uced by the boundary layer are not considered. In the case of liquids, it is shown that the momentum deficit of the injectant relative to the free stream may play a larger part in producing the side force than the volume generation by vaporization and reaction. The analytical results are compared with those obtained from experiments in a wind tunnel and in nozzles. (Author)

APPLICATION OF A DISCRETE VELOCITY MODEL TO THE BOLTZMANN EQUATION IN SHEAR FLOWS( )

1 edition published in 1963 in English and held by 1 WorldCat member library worldwide

The application of a simple discrete velocity model to low Mach number Couette and Rayleigh flow is investigated. In the model, the molecular velocities are restricted to a finite set and in this study only eight equal speed velocities are allowed. The Boltzmann equation is reduced by this approximation to a set of coupled differential equations which are shown to be identical in form to those produced when the same approximation is applied to the Krook equation. The fluid velocity and shear stress in Couette flow are in approximate accord with those of Wang Chang and Uhlenbeck and of Lees over the complete range of Knudsen number

Investigations of the Motion of Discrete-Velocity Gases by Cellular Automata( Book )

1 edition published in 1988 in English and held by 1 WorldCat member library worldwide

A model of molecular gasdynamics with discrete components of molecular velocity has been implemented for parallel computation, and two test problems have been calculated. It is shown that fewer than ten values of each component of molecular velocity are necessary to produce accurate results in calculations by direct-simulation Monte-Carlo methods of rarefied-gas flows involving moderately strong shock waves. Thus significant savings in memory required to store the molecular velocities are realized. Most cellular automata intended to describe fluid motion simulate single-speed particles moving on square or hexagonal lattices. It is clear that with only one allowed molecular speed, temperature or energy cannot be specified independently of the velocity. The present paper describes the results of an exploratory investigation of heat conduction and shock wave formation with the two-dimentional model. The irreversible macroscopic behavior of this microscopically reversible system is also examined. Keywords: Molecular gasdynamics; Direct simulation; Monte Carlo method; Cellular automata. (mgm)
