Abstract : This work aims to numerically study the stabilization of flame in a MEMS based methane-air adiabatic micro-combustor. Three different micro-combustor geometries were computationally simulated using premixed methane air-fuel in quartz micro-combustor with different configurations in order to determine the optimal micro-combustor design for the highest efficiency. The study was conducted to determine the design and characteristics of flame stabilization behavior in the micro-combustor. ANSYS Fluent application software was used to simulate the models. Premixed fuel of methane-air is used to stabilize the flame with a stoichiometric ratio of 0.6. The design of micro-combustor is modified by creating backward steps in the model, in order to create a recirculation zone to slow down the flow, which intends to stabilize the flame at center of the micro combustor. The model was analyzed for different inlet velocities, ranging from 0.5 to 2 m/s, of the premixed fuel. It is clear from the analysis that a micro-combustor with one backward step stabilizes the flame with highest efficiency for different inlet velocities.
