| Abstract | ||
| The effect of oxygen enrichment on the laminar flame speed of (butane – oxygen – nitrogen) premixed mixture. The measurement system is designed to measure the laminar flame speed using a tube – method and optical technique (photodiode).The laminar flame speed results were obtained at atmospheric pressure, initial temperature 301K, three level of oxygen concentration (0.21, 0.23 & 0.25) and equivalence ratio ( 0.6 – 1.4 ). All the measurements were carried out at pre-pressure period to use “density ratio method” for the calculation of laminar burning velocity. The adiabatic flame temperature, flame thickness and Zel’dovich number have been calculated theoretically. Validation of experimental work is approved by comparison measured values of laminar burning velocity for (butane – air) mixtures with the available published data. Good agreements are obtained in its comparison with the literature results employed in the present work are successful and precise. | ||
