The Effect Of Initial Temperature On Burning Velocity Of Methane, Propane, Lpg And Iso Butane - Air Mixtures
MetadataShow full item record
In present work, the burning velocity of a fuel - air mixtures varies with equivalence ratio, temperature and number of carbon atoms. Laminar flame speed have been measured experimentally inside a tube using the optical technique. The experimental work was carried out in a pre-pressure period in order to use density ratio method for calculation of laminar burning velocity. Mixture strength, unbumed mixture temperature and number of carbon atoms dependence of burning velocity is represented by empirical functions over the ranges of <(> = 0.6 - 1.5, Tu = 298-348 °K and He = 1-4 atoms, all at pressure of (1 atm). In overlapping ranges, the results agree well with those previously published.
