WebMay 26, 2024 · An increase in flame speed by 26% (i.e., from 13.5 to 17.1 m/s) reduces the indicated fuel consumption by 7.8% and an increase in efficiency by 8.3% (at α = 1). This is explained by the fact that an increase in the flame speed leads to an increase in the completeness and intensity of fuel combustion in the combustion chamber. The flame speed is the measured rate of expansion of the flame front in a combustion reaction. Whereas flame velocity is generally used for a fuel, a related term is explosive velocity, which is the same relationship measured for an explosive. Combustion engineers differentiate between the laminar flame speed and turbulent flame speed. Flame speed is typically measured in m/s, cm/s, etc.
