Flame kinetics
Webspherical flame collapses resulting in a reversal in the gas velocities near the flame zone. Detailed chemical kinetics description was found to have only a small effect on the flame radius & flame temperature predictions. However, it is extremely important to understand the extinction mechanisms. I.

WebJul 22, 2015 · The present paper is concerned with the development of a detailed chemical kinetic mechanism to describe the flame inhibition chemistry of the fire suppressant 2-bromo-3,3,3-trifluoropropene (2-BTP). Currently 2-BTP is considered as a fire suppressant to replace CF3Br for use in aircraft cargo bays. Cup burner tests indicate that 2-BTP is an ... WebJan 18, 2024 · The isothermal kinetics of curing was described by means of model fitting and the isoconversional approach (Friedman method). Accurate n-order approximation was obtained for all systems under study. In particular, the 2-order equation fits well with the main part of curing excluding high degrees of conversion.
