On scalar dissipation and partially premixed flame propagation

Combustion Science and Technology, 2003
Measurements of the scalar dissipation rate in the region immediately upstream of a lifted jet flame are presented. The scalar dissipation is determined in this isothermal region from a planar measurement of a two-dimensional conserved scalar (jet fluid) using laser Rayleigh scattering. Fields of the scalar dissipation rate are presented in addition to

Flame stretch effects on partially premixed flames

Combustion and Flame, 2000
Abstract Flame stretch is an important characteristic of flame behavior that arises due to flow motion and nonuniformity, and flame curvature. Various investigators have obtained different expressions for flame stretch by employing dissimilar analytical approaches for diverse flame configurations.

LaminarTriple Flames in Partially Premixed Opposed Flows

Combustion Science and Technology, 1998
Presented is an asymptotic analysis of premixed laminar flames in opposed streams under circumstances of fast chemistry and/or low rates of strain and of high Reynolds numbers. In this case there exist three distinct reaction layers, two premixed and one nonpremixed, the latter centered on the stagnation plane.

Model Predictive Control of Partially Premixed Combustion

2010
Partially premixed combustion is a compression ignited combustion strategy where high exhaust gas recirculation (EGR) levels in combination with early or late injection timing result in a prolonged ignition delay yielding a more premixed charge than with conventional diesel combustion. With this concept it is possible to get low smoke and NOx emissions
