Summary:

A two dimensional flame front visualisation technique, based on Mie scattering from particles dispersed in the combusting mixture, has been developed. The technique was used in an I.C. engine simulator to study the freely propagating flame in premised combustion. It is shown that flame front structures can be resolved for scales as low as 2104 m. These scales were observed at 1500 RPM where velocity fluctuations are known to be on the order of 6 m/s.For lean propane combustion, peninsulas and pockets of unburned mixture are observed in the postflame regions at 600 RPM. Higher turbulence levels increase the global flame front area by creating flame front corrugations of various length scales. Evidence of flame front wrinkles having sizes comparable to previously reported flame thickness in engines suggests that I.C. engine models should take into account the interaction between the velocity field and the detailed structure of the diffusive-reactive flame front zone
