This paper presents a numerical investigation of the mixing of methane and air inside a 5mm high and 40 mm long 2-D channel type microcombustor. Two fuel-air injection schemes are studied at different equivalence ratios. Configuration-I injects methane from an axially located port, whereas configuration-II injects methane from two radially located opposing ports. The velocity field and local methane mixture fractions indicate that the configuration-I provides a superior mixing for lean, stoichiometric and rich equivalence ratios. However, configuration-II yields sufficient mixing only at a fuel rich condition. Also, despite geometrical symmetry of the chamber, flow-fields are highly asymmetric at a lean condition in both configurations.
