Abstract
Measurement of laminar burning speed is complex and costly. Therefore, engineering correlations of this thermo-chemical property with other simpler-to-measure fundamental combustion properties, such as minimum ignition energy, are desired. Two different correlations between laminar burning speed and minimum ignition energy have been developed. The first correlation is of the form Sl = a minimum ignition energy−1/3 and the second correlation of the form Sl = b minimum ignition energyc, where a, b, and c are the fitting constants. The accuracies of these fits were close to each other.
