| Popis: | International audience; A potential implication of Volatile Organic Compounds (VOCs) emitted by vegetal species has been introduced in the literature to explain accelerating forest fires. These fires are characterized by the sudden increase of the rate of spread and of the energy released by the fire front. The main purpose of this paper is to determine the combustion characteristics of a major VOC emitted by Thymus vulgaris needles, namely p-cymene. The emission of this compound is studied for the temperature range 343-453 K with an emission peak observed at 443 K. Laminar burning speeds, Markstein lengths and flame thicknesses are determined using outwardly propagating spherical flames in a combustion vessel at atmospheric pressure. The effects of equivalence ratio (0.8 to 1.4) and unburned gas temperature (358 to 453 K) are investigated. Results are compared to experimental data of α-pinene and to computed data of two fuels, JP-10 and n-decane obtained with the PREMIX code of the CHEMKIN package. |
