✦ Synopsis

An experimental study on effects of temperature and pressure on the burning velocity of methane-air and hydrogen-air mixtures has been conducted by using the spherical bomb technique proposed by the present authors. The ranges of measurement covered the equivalence ratio from 0.8 to 1.3 for methane-air, and from 0.5 to 4.0 for hydrogen-air mixtures. The mixture temperature was varied from 291 to 500K, while the pressure from 0.5 to 30 atm for methane-air and from 0.5 to 25 atm for hydrogen-air mixtures. The empirical equations for the burning velocities have been obta"ined. The obtained burning velocities were correlated by the Arrhenius form expression, which is based on the flame theory with a one-step kinetics, to yield the apparent order and activation energy of the overall reaction. The derived values were compared with those obtained by other investigators.
