Diagnostics for the Combustion Science Workbench

Description

As the cost of computers declines relative to outfitting andmaintaining laser spectroscopy laboratories, computers will account foran increasing proportion of the research conducted in fundamentalcombustion science. W.C. Gardiner foresaw that progress will be limitedby the ability to understand the implications of what has been computedand to draw inferences about the elementary components of the combustionmodels. Yet the diagnostics that are routinely applied to computerexperiments have changed little from the sensitivity analyses includedwith the original chemkin software distribution.

Description

As the cost of computers declines relative to outfitting andmaintaining laser spectroscopy laboratories, computers will account foran increasing proportion of the research conducted in fundamentalcombustion science. W.C. Gardiner foresaw that progress will be limitedby the ability to understand the implications of what has been computedand to draw inferences about the elementary components of the combustionmodels. Yet the diagnostics that are routinely applied to computerexperiments have changed little from the sensitivity analyses includedwith the original chemkin software distribution. This paper describessome diagnostics capabilities that may be found on the virtual combustionscience workbench of the future. These diagnostics are illustrated bysome new results concerning which of the hydrogen/oxygen chain branchingreactions actually occur in flames, the increased formation of NOx inwrinkled flames versus flat flames, and the adequacy oftheoreticalpredictions of the effects of stretch. Several areas are identified wherework is needed, including the areas of combustion chemistry and laserdiagnostics, to make the virtual laboratory a reality.
