Numerical simulation of reactive flow
by Elaine S Oran
(
Book
)
19 editions published between 1987 and 2005 in English and held by 578 WorldCat member libraries worldwide "This book takes account of the explosive growth in computer technology and the greatly increased capacity for solving complex reactiveflow problems that have occurred since the first edition of Numerical Simulation of Reactive Flow was published in 1987. It presents algorithms useful for reactiveflow simulations, describes tradeoffs involved in their use, and gives guidance for building and using models of complex reactive flows. The text covers both new topics and significant changes in the treatment of radiation transport, coupling, grids and numerical representations, and turbulence. Chapters are arranged in three broad sections: an introductory short course on modeling and numerical simulation; advanced topics in numerical simulation of reactiveflow processes; and, finally, simulations of complex reactive flows." "This new edition is an indispensable guide to how to construct, use, and interpret numerical simulations of reactive flows. It will be welcomed by advanced undergraduate and graduate students, as well as a wide range of researchers and practitioners in engineering, physics, and chemistry."BOOK JACKET

Numerical Solution of Continuity Equations
(
Book
)
1 edition published in 1976 in English and held by 1 WorldCat member library worldwide This paper compares and contrasts the six general methods available for solving the time dependent continuity equation numerically. Since finitedifference techniques naturally arise as the most generally applicable solution methods, consideration is given to solving the major remaining difficulties encountered in the general application of Lagrangian and Eulerian finite differences. In the former, triangular mesh cells with free reconnections are suggested as a complicated but serviceable solution to the Lagrangian grid distortion problem. In the latter, nonlinear monotonic difference schemes are introduced as the natural way to avoid the Eulerian positivity problem. FluxCorrected Transport techniques, the most developed and efficient of the positive (monotone) finitedifference approaches, are described with examples. (Author)
NonPhysical Self Forces in Electromagnetic PlasmaSimulation Algorithms
(
)
1 edition published in 1972 in English and held by 1 WorldCat member library worldwide The paper describes a simple algorithm for removing nonphysical self forces from two popular electromagnetic plasma simulation models. This algorithm also has two additional features; it considerably reduces shortwavelength noise and unwanted numerical fluctuations, and permits faster integration of the particle orbit equations by roughly a factor of two

A OneDimensional TimeDependent Model for Flame Initiation, Propagation and Quenching
by K Kailasanath
(
Book
)
1 edition published in 1982 in English and held by 1 WorldCat member library worldwide This report describes a onedimensional, timedependent, Lagrangian numerical model developed to study the initiation, propagation and quenching of laminar flames. A number of new approaches and algorithms as well as input parameters used in the model are discussed. Calculations of initiation and minimum ignition energies in hydrogenoxygennitrogen mixtures are presented along with calculations of the burning velocity of hydrogen in air. (Author)

The Stability and Multiplicity of the Monotonic Lagrangian Grid
(
)
1 edition published in 1997 in English and held by 1 WorldCat member library worldwide The Monotonic Lagrangian Grid (MLG) is a data structure in which nodes are ordered in a monotonic way such that those nodes which are close in physical space also have nearby indices in the data structure arrays. An MLG ordering for a given system of nodes, as defined by the monotonicity constraints, is not unique. For all but the smallest systems, the number of allowed orderings is extremely large with many of the possible MLG's so badly structured that they lead to poor results when used in physical calculations. A wellstructured MLG ordering is one that corresponds well to the physical ordering of the system. This paper shows that the majority of the MLG's for a given set of node locations are poorly structured, but that the small fraction which are wellstructured tend to be extremely stable against perturbations of the node positions. It is this extreme stability of the wellstructured MLG's that is responsible for both the utility of this approach in particlebased simulations and the success of stochastic grid regularization, a technique for restructuring from a poorly structured to a wellstructured MLG. The high probability of encountering a wellstructured MLG when the node dynamics is complex, even without stochastic grid regularization, is a result of this relative stability
Theoretical and Computational Approach to Modeling Flame Ignition
(
Book
)
1 edition published in 1979 in English and held by 1 WorldCat member library worldwide In this paper, timedependent results obtained from a simplified but nonlinear analytic similarity solution and a detailed numerical simulation are used to study the relations between the fundamental processes occurring in the very early stages of flame ignition in homogeneous premixed gases. The parameters which may be varied are the composition of the mixture, the initial radius of energy deposition R sub 0, the duration of the heating TAN SUB 0, and the total energy deposited in the system E sub 0. The similarity solution plus the ignition delay times Tau sub c for the fueloxidizer mixture as a function of temperature can be used to calculate whether or not a given energy source is adequate to ignite the system. This simple procedure may then be calibrated using the timedependent NRL detailed reactive flow models. The models include the thermophysical properties of the mixture, a full chemical kinetics scheme, the nonlinear convection of selfconsistent fluid dynamics and the matrix molecular diffusion coefficients for the individual species. Results are presented for a selected mixture of H2O2N2 for two values of R sub 0 which show that a model must be constructed for a quench volume in order to complete the similarity solution calibration.

Studies of Plasma Containment in Cusp Magnetic Field for Two Liner Shapes
(
Book
)
1 edition published in 1974 in English and held by 1 WorldCat member library worldwide This note summarizes preliminary computational studies made of plasma confinement in a cusp magnetic field created by liners or coils of two different shapes. The amount of plasma contained was calculated at several radial positions of the liner to model a liner moving inward. It was found that the liner shape and position are important in achieving the lowest ratio of field to plasma energy and hence maximizing the efficiency of the compression. The results suggest further studies requiring a more sophisticated program now under development
