Diagnostic for the characterization of nanometric structures in high temperature reactive systems [PDF]

, 2008
It is now well know that the fraction of particulate mater in the ambient air defined as ultrafine particles can be considered the most critical for adverse human health effects because of their chemical composition and the ability of these particles to ...

Turbulent flame development in a high-pressure combustion vessel [PDF]

, 2005
The objective of this work was to extend the range of turbulent burning velocities presented in the literature by performing new measurements at elevated pressures over a range of turbulent velocities, u' (r. m. s. deviation from the mean velocity).

Numerical modelling of a CAN combustion chamber with swirler using probability density functions (PDF) and eddy dissipation model (EDM)

Results in Engineering
This study employs a well-established experimental setup, involving a can combustor with swirling, recirculating, and turbulent reactive flow to evaluate the performance of combustion and turbulence modelling within the combustion chamber.

CHEMISTRY-TURBULENCE COUPLING IN A MODEL OF INHOMOGENOUSLY PREMIXED COMBUSTION

TASK Quarterly, 2003
Results of work on an extension of the turbulent flame speed model used for a mathematical description of partially premixed combustion are presented. The approach is based on the concept of internal coupling between the turbulence of the mixed fuel and

Premixed Turbulent Combustion in Opposed Streams

, 1992
Premixed turbulent combustion in opposed streams has been studied experimentally by the use of two component laser doppler aneomometry. This flow geometry is part of a class of stagnating flows used to study turbulent combustion in recent years. It does not involve any surface near the flames because of the flow symmetry thus circumventing many of the ...

Soot and radiation modelling in buoyant fires [PDF]

, 1990
This study seeks to advance present modelling capabilities in respect of soot and thermal radiation emission from fires. Such developments are crucial to the improved estimate of the hazard potential of accidental fires.
