Abstract
Measurements of the laminar flame speeds of n-butane/air mixtures with and without the addition of small amounts of hydrogen were made using a flat flame burner at atmospheric pressure. The ranges of measurement covered the equivalence ratio from 0.52 to 1.20, hydrogen enrichment of 0% to 6% (hydrogen-to-fuel mass ratio), and corrected initial temperature of 270-410 K. Over the range studied, the results can be fitted within an estimated error of ± 10% by the functional form ub(φF,RH,TR) ub(1.04,0,298)= ub(φF,0,298) ub(1.04,0,298)+2.18 RH TR 298β(φF) where φF is an effective fule/air equivalence ratio, RH indicates the relative amount of hydrogen addition, and β(φF) = 2.05 + 1.4 (φF - 1). The values for the pure gases were in good agreement with previous experimental results.
