Optimally-reduced kinetic models: reaction elimination in large-scale kinetic mechanisms

Autor: William H. Green, Binita Bhattacharjee, Paul I. Barton, Douglas A. Schwer

Publikováno v: Combustion and Flame. 135:191-208

A new optimization-based approach to kinetic model reduction is presented. The reaction-elimination problem is formulated as a linear integer program which can be solved to guaranteed global optimality. This formulation ensures that the solution to t

An adaptive chemistry approach to modeling complex kinetics in reacting flows

Autor: Douglas A. Schwer, William H. Green, Pisi Lu

Publikováno v: Combustion and Flame. 133:451-465

Existing algorithms use a single chemical kinetic model over the entire domain of a reacting flow simulation. However, it is well known that the chemistry varies significantly in different regions of a flame. For combustion and other reacting flows w

A consistent-splitting approach to computing stiff steady-state reacting flows with adaptive chemistry

Autor: Pisi Lu, Viriato Semiao, Douglas A. Schwer, William H. Green

Publikováno v: Combustion Theory and Modelling. 7:383-399

Splitting techniques have been used extensively for computing reacting flows with detailed chemistry. Nevertheless, there are still some open questions with respect to efficiency and the error introduced by splitting. In this paper, the accuracy and

On upgrading the numerics in combustion chemistry codes

Autor: Paul I. Barton, Douglas A. Schwer, John E. Tolsma, William H. Green

Publikováno v: Combustion and Flame. 128:270-291

A method of updating and reusing legacy FORTRAN codes for combustion simulations is presented using the DAEPACK software package. The procedure is demonstrated on two codes that come with the CHEMKIN-II package, CONP and SENKIN, for the constant-pres

Autor: H.-H. Carstensen and, David M. Matheu, Paul I. Barton, Douglas A. Schwer, Binita Bhattacharjee, Raman Sumathi, and J. Song, Anthony M. Dean, Jeffrey M. Grenda, William H. Green

Publikováno v: Industrial & Engineering Chemistry Research. 40:5362-5370

The combustion, oxidation, and pyrolysis chemistry of even simple light hydrocarbons can be extremely complex, involving hundreds or thousands of kinetically significant species. Even relatively minor species can play an important role in the formati

Blast Mitigation Using Water Mist

Autor: John P. Farley, Frederick W. Williams, Douglas A. Schwer, Michael S. Lindsay, Jean L. Bailey

A series of experiments demonstrating the mitigation of water mist on the over-pressure effects of a TNT detonation have been conducted A series of TNT charges, 0.9 kg (2 lb), 2.2 kg (5 lb) and 3.2 kg (7 lb), were detonated both with and without empl
