Flame stability enhancement is achieved as the flame structure is transformed from diffusion to partially premixed type. The present work is the first attempt to introduce micro-mixing in micro-scale combustion. A slot (micro-mixing slot) is provided in the centrally slotted bluff body to enable a small quantity of air gets mixed with fuel which subsequently enhances the flame stabilization in a micro-combustor. The angle of the micro-mixing slot is optimized by considering varied inlet velocity and equivalence ratio range.

The range obtained is <strong>2 &lt; φ_inter &lt; 5</strong> for cold flow to achieve stable flames. The transformation of flame structure from diffusion to partially premixed type and the subsequent flame stability enhancement was analyzed by comparing combustors with and without micro-mixing.

The trend in flame dynamics and wall temperature distribution by varying inlet velocity (at φ_g = 1.0) and global equivalence ratio (at V_air = 1m/s) were analyzed and furthermore the lean stability limit was determined. The lift-off mechanism was investigated at stoichiometric and lean global equivalence ratios - φ_g = 1.0, 0.8 and 0.5. Even at the lift-off condition, heat transfer from flame to bluff body tip was prominent, which enabled enhanced flame stabilization.
