TL;DR: In this paper, the results of studies on the ignition and behavior of cylindrically symmetric, laminar diffusion flames of methane and propane in quiescent air under microgravity conditions were presented.

TL;DR: In this article, a subset of the publicly available NASA Structure and Liftoff in Combustion Experiments (SLICE) microgravity and normal gravity nitrogen-diluted laminar diffusion methane flames has been considered, and a method to extract quantitative CH * concentration information from the SLICE raw data is demonstrated.

TL;DR: In this article, the authors investigated radiative extinction of spherical diffusion flames and found that radiative heat loss was dominated by the combustion products downstream of the flame and was found to scale with flame surface area, not volume.

TL;DR: In this article, a linear relationship between adiabatic flame temperature and Zst was found to be in qualitative agreement with a simple theory that assumes soot inception requires the local C/O atom ratio and temperature to be above threshold values, (C/O)c and Tc.

TL;DR: In this paper, a set of microgravity coflow diffusion flame data was obtained, covering a range of conditions from weak flames near extinction to strong, highly sooting flames, and enabled the study of gravitational effects on phenomena such as liftoff, blowout and soot formation.
