On the laminar burning speeds and combustion characteristics of a-pinene-air premixed flames involved in accelerating forest fires

Résumé

The main purpose of this paper is to determine the laminar burning velocities and Markstein lengths of α-pinene/air premixed flames using the spherical expanding flames method. Experiments are carried out in a spherical vessel at atmospheric pressure. The effects of equivalence ratio (0.7 to 1.4) and unburned gas temperature (353 to 453 K) are studied. Unstretched propagation speeds and Markstein lengths are obtained using a nonlinear methodology. A correlation is developed to calculate laminar burning speeds as a function of equivalence ratio and temperature. The PREMIX code is used to compute laminar flame speeds with the San Diego chemical kinetic mechanism of JP-10, which is an isomer of α-pinene. The measured values are compared to those of literature.
