Abstract

Ignition is a fundamental process for combustors. Its success or failure depends on flow properties and mixture concentration. The existence of regime where the flow velocity is less than that of the flame has a decisive impact on flame stability. If the bulk of flow has high velocity, flame might be quenched or be swept by the flow. Quenching occurs when the heat released was less than the heat lost to the mixture. Eddies created by the injection pattern create vortices that aided the mixing of the fuel and oxidizer helped anchor the flame
