An experimental study has been performed in a disc-shaped constant volume chamber in order to investigate the effect of turbulence intensity on flame propagation and to clarify the mechanism of reduction of the burning time by the turbulence. Gaseous mixtures tested were methane/air and liquefied petroleum gases (LPG)/air mixtures. The turbulent field was generated by using the multiple injection method. The turbulence intensity in the mixture was varied by changing the ignition timing. The results showed that (1) The scales of turbulence on the flame surfaces decrease with the increase of turbulence intensity; (2) The burning time decreases with the increase of turbulence intensity; (3) The maximum combustion pressure increases with the increase of turbulence intensity because the total heat loss decreases with the decrease of the burning time. Generating some disturbance in the mixtures before ignition is very effective method for the reduction of burning time.
