Laminar Burning Velocity of LPG-Air Mixture at Elevated Temperatures

Laminar burning velocity of liquefied petroleum gas (LPG) air mixtures at high temperatures is extracted from the planar flames stabilized in the preheated meso-scale diverging channel. The experiments were carried out for a range of equivalence Computational predictions of burning velocity and detailed flame structure were performed using PREMIX code with USC mech 2.0. The present data are in very good agreement with both experimental and computational results available. Peak burning velocity was observed for slightly rich mixtures even at higher mixture temperatures. The minimum value of temperature exponent is observed for slightly rich mixtures.
