Explosion regions of acetone and alcohol/inert gas/air mixtures at high temperatures and atmospheric pressure
TL;DR: In this article, the explosion regions of all combustible/inert gas/air mixtures were calculated with the method of constant adiabatic flame temperature profiles (CAFTP), using the flame temperature profile along the explosion region boundary curve of each combustible /N2/air mixture as a reference to determine the explosion areas of all mixtures with inert gases other than N2 at different initial temperatures.

PDF Simulations of the Ignition of Hydrogen/Air, Ethylene/Air and Propane/Air Mixtures by Hot Transient Jets
TL;DR: In this paper, a numerical investigation is carried out to study ignition events of different premixed stoichiometric fuel/air mixtures by hot exhaust gas jets by using a stand-alone probability density function (PDF) method in connection with a projection method to calculate the mean pressure is used to model the turbulent flow.

A PDF projection method: A pressure algorithm for stand-alone transported PDFs
TL;DR: In this paper, a new formulation of the projection approach is introduced for stand-alone probability density function (PDF) methods, which is suitable for applications in low-Mach number transient turbulent reacting flows.

Explosion regions of 1,3-dioxolane/nitrous oxide and 1,3-dioxolane/air with different inert gases - Experimental data and numerical modelling
TL;DR: In this article, experimental determination and modelling investigations for the explosion regions of 1,3-dioxolane/inert gas/N2O and 1, 3diox-olane-inert gases/air mixtures were carried out and compared.
