Coupling of Macroscale and nanoscale simulations of soot formation in a diffusion flame

Abstract : Experimental studies have suggested that soot particles formed along different streamlines in a diffusion flame may have different morphologies. However, the uncertainties linked to the sampling and their analysis make difficult the quantification of these morphological differences. In this work, this problem is explored from a numerical point of view thanks to a coupling of nanoscale and macroscale simulations. This shows remarkably larger and more compact aggregates near the wings of the flame compared to its centerline. The analysis of morphological parameters such as anisotropy, monomers overlapping and coordination number reveals the complex morphology of soot and shows the presense of chain-like aggregates along the different streamlines of the flame.
