摘      要：Laminar flame speeds of hydrogen/natural gas/air mixtures have been measured over a full range of fuel compositions(0-100%volumetric fraction of H_(2))and a wide range of equivalence ratio using Bunsen *** sensitivity scientific CCD camera is use to capture the image of laminar *** reaction zone area is employed to calculate the laminar flame *** initial temperature and pressure of fuel air mixtures are 293 K and 1 *** laminar flame speeds of hydrogen/air mixture and natural gas/air mixture reach their maximum values 2.933 and 0.374 m/s when equivalence ratios equal to 1.7 and 1.1,*** laminar flame speeds of hydrogen/natural gas/air mixtures rise with the increase of volumetric fraction of ***,the increase in laminar flame speed as the volumetric fraction of hydrogen increases presents an exponential increasing trend versus volumetric fraction of *** formulas to calculate the laminar flame speeds of hydrogen,natural gas,and hydrogen/natural gas mixtures are also *** these formulas,the laminar flame speed at different hydrogen fractions and equivalence ratios can be calculated.
