Journal ArticleDOI
HRTEM evaluation of soot particles produced by the non-premixed combustion of liquid fuels
Maria L. Botero,Dongping Chen,Silvia Gonzalez-Calera,David A. Jefferson,Markus Kraft,Markus Kraft +5 more
TL;DR: In this paper, the morphology and nanostructure of soot particles as a function of fuel type in a laminar diffusion flame were studied, and an image analysis algorithm was developed to calculate the fringe length, tortuosity and inter-fringe spacing from HRTEM images.
Journal ArticleDOI
Synergistic combustion of droplets of ethanol, diesel and biodiesel mixtures
TL;DR: In this paper, free-falling droplets of ethanol, diesel, (castor oil) biodiesel, and their mixtures were experimentally examined in a high-temperature combustion chamber.
Journal ArticleDOI
Internal structure of soot particles in a diffusion flame
Maria L. Botero,Yuan Sheng,Jethro Akroyd,Jacob W. Martin,Jochen A.H. Dreyer,Wenming Yang,Markus Kraft,Markus Kraft +7 more
TL;DR: In this article, the internal structure of a coflow diffusion flame was studied using high-resolution transmission electron microscopy, and the radial distribution of fringes within the particles was calculated from the fringe lengths, assuming planar peri-condensed PAHs.
Journal ArticleDOI
PAH structure analysis of soot in a non-premixed flame using high-resolution transmission electron microscopy and optical band gap analysis
Maria L. Botero,Erin M. Adkins,Silvia Gonzalez-Calera,Houston Miller,Markus Kraft,Markus Kraft +5 more
TL;DR: In this article, a system of non-premixed liquid fuel flames supported on a wick-fed, smoke point test burner (ASTM D1322-08) was characterized by in-situ visible light extinction and thermophoretically-sampled high-resolution transmission electron microscopy measurements, HRTEM.
Journal ArticleDOI
Sooting tendency of paraffin components of diesel and gasoline in diffusion flames
TL;DR: In this article, the influence of chemical structure on the sooting characteristics of some paraffin class hydrocarbons which are found in gasoline and diesel fuel is studied experimentally, and the results show that the PSD of normal, iso and cyclo paraffins evolve in a similar way with flame height.
