TL;DR: In this article, a combination of microgravity experiments and computational simulations were used to study effects of diluents on the near-limit properties of laminar, premixed hydrogen/air flames.

TL;DR: In this article, the vertical distribution of temperature above the center of a fuel is compared with temperature profiles for square fuels and for line fuels, and a practical criterion for the approximation of rectangular fuels by square and line source is proposed.
Abstract: Measurements of flame height and temperature distribution above fuel surface were made on rectangular propane burners i,.p a huge calm eln~os~72.' Flame height is represented as a function of Q d; Q/ p CpT g AB , where A and B are the length of the shorter and m'1'onger ~ide 0 of a fuel respectively. Vertical distribution of temperature above the center of a fuel is compared with temperature profiles for square fuels and for line fuels. Finally a practical criterion for the approximation of rectangular fuels by square and line source is proposed. key words: turbulent flame, flame height, temperature, aspect ratio.

TL;DR: In this paper, a new model for condensation of polycyclic aromatic hydrocarbons (PAHs) on the surface of soot particles is developed based on the reversibility of the process.

TL;DR: In this paper, the uncertainties associated with the extraction of laminar flame speeds through extrapolations from directly measured experimental data were assessed using one-dimensional direct numerical simulations with focus on the effects of molecular transport and thermal radiation loss.
