Numerical simulation of reactive flow

Book
)
19 editions published between 1987 and 2005 in English and held by 581 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

Detailed modelling of combustion systems
by Elaine S Oran
(
Book
)
3 editions published between 1980 and 1981 in English and held by 8 WorldCat member libraries worldwide The purpose of this paper is to acquaint the reader with some of the basic principles of detailed modelling as applied to combustion systems. Detailed modelling is also known as numerical simulation. It can be used to describe the chemical and physical evolution of a complex reactive flow system by solving numerically the governing timedependent conservation equations for mass, momentum and energy. Solving these equations requires input data such as the species present, the chemical reactions that can occur, transport coefficients for viscosity, thermal conductivity, molecular diffusion, and thermal diffusion, the equation of state for the various materials present, and a set of boundary, source and initial conditions. Given this information, the equations contain in principle all the information we might want from the largest macroscopic space scales down to the point where the fluid approximation itself breaks down. Flame, detonation, turbulence phenomena, and all multidimensional effects are included in the solutions of these equations. An important goal of detailed modelling is to develop a computational model with a wellunderstood range of validity. This model can then be used in a predictive role to evaluate the feasibility and validity of new concepts. It can also be used to interpret experimental measurements, to extend our knowledge to new parameter regimes, and perhaps as an engineering design tool. Throughout these various applications, the model may serve as an excellent way to test our understanding of the interactions of the individual physical processes which control the behavior of a reactive flow system

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
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

The Nonlinear Aspects of the RayleighTaylor Instability in Laser Ablation
by M. H Emery
(
Book
)
1 edition published in 1982 in English and held by 1 WorldCat member library worldwide We report on our investigation of the RayleighTaylor (RT) and KelvinHelmholtz (KH) instabilities in laser ablatively accelerated targets for single mode perturbations for a series of wavelengths in the parameter regime 1/2 less than or equal to lambda/delta R less than or equal to 10, where lambda is the wavelength of the perturbation and delta is the cold foil thickness. We find linear growth rates well below classical values (by a factor on the order of 34). We also find a cutoff in the growth rates for wavelengths less than the foil thickness. The striking result is the dominance of nonlinear effects; i.e., the KH instability for short wavelength perturbations. Although the linear growth rates increase as k1/2 up to the cutoff, the KH rollup dominates at large k, drastically reducing the penetration rate of the dense spike below its free fall value and effectively doubling the aspect ratio of the foil. In other words, it is the long wavelength perturbations that are most effective in destroying the symmetric implosion of the shell
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)
