| Abstract | ||
| In present work, the burning velocity of hydrogen-Air mixtures varies with hydrogen concentration and initial temperature of the unburned mixture. Laminar flame speed has been measured experimentally inside tube using the optical technique. The experimental work was carried out in a pre-pressure period in order to apply the density ratio method for calculation of laminar burning velocity. Mixture strength and unburned mixture temperature dependence of burning velocity is represented by empirical function over the ranges of hydrogen concentration (xH2 = 10 – 70 %) and unburned temperature (Tu = 298K– 348K), which is extended to (473K) through the previously published data all at a pressure of (1 atm). In overlapping ranges, the results show good agreement with those previously published. | ||
