“…hole in the middle, is placed at the tube outlet to avoid air entrainment inside the tube. This wire mesh layer is not expected to create any pressure buildup in the tube, which can affect SL measurements, as the flame initiated [4,9,15],…”

“…Recently, SL has been measured using counter flow flame [10], spherical flame in a closed vessel [10][11][12][13], Bunsen burner [14], and the tube method [4,9,15]. The latter is the simplest method with reasonable accuracy comparing with the other methods, and it has been used in the present study.…”

“…The only disadvantage with this method is the uncertainties in the measured SL caused by the heat transfer from the flame front to the tube wall. However, this error becomes insignificant when special tube material is used such as quartz glass or plastic [9,15]. Laminar flame speeds have been extensively studied for a large number of liquid and gaseous fuels [16][17][18][19][20][21][22][23][24], In addition, a considerable attention has been given to measure SL of some alternative gaseous fuel mixtures such as bio gas, which consists mainly of methane (CH4) and carbon dioxide (C 02) [25,26].…”

Global warming and the ever increasing emission levels o f combustion engines have forced the engine manufacturers to look fo r alternative fuels fo r high engine performance and low emissions. Gaseous fuel mixtures such as biogas, syngas, and liquefied petroleum gas (LPG) are new alternative fuels that have great potential to be used with combustion engines. In the present work, laminar flame speeds (S ,j o f alternative fuel mixtures, mainly LPG (60% butane, 20% isobutane, and 20% propane) and methane have been studies using the tube method at ambient conditions. In addition, the effect o f adding other fuels and gases such as hydrogen, oxygen, carbon dioxide, and nitrogen on SL has also been investigated. The results show that any change in the fuel mixture composition directly affects S,_. Measurements ofSL o f CHflLPG-air mixtures have found to be about 56cm/s at 0 = 1.1 with 60% LPG in the mixture, which is higher than SL o f both pure fuels at the same 0. Moreover, the addition ofH2 and 0 2 to the fuel mixtures increases SL notably, while the addition o f C 0 2IN2 mixture to the fuel mixture, to simulate the EGR effect, decreases SL o f CHflLPG-air mixtures.
