Abstract : Burning properties of premixed H2/air mixtures in single-stepped micro-combustor were numerically analysed. A detailed H2/air combustion mechanism of with nine species and 21 elementary reactions was used to model the combustion chemistry. Both laminar and turbulent models are considered for the analysis. The effect of inlet velocity (v) and step ratio on combustion characteristics and outer wall temperature (To_w) of combustor was studied. As step ratio is increased, the outer wall temperature of the combustor decreases due to the effect of lesser heat release rate and lesser transfer of heat flux for higher step ratio cases.
