Abstract
In this study, stable range of self-ignition for the micro-combustion of CH4 and CH4-H2 mixtures have been investigated over platinum-coated micro catalytic honeycomb reactor by CFD technique using CHEMKIN and ANSYS17.2 Packages. A certain amount of heat is furnished from outside at constant temperature with an external electric furnace to investigate localized self-ignition temperature. This investigation studies the effect of flow rate and mixture strength. Noting that, Ignition of mixtures occurs at same temperature for different mass flow rates of CH₄-Air mixtures, while it is decreased for increased flow rates of CH₄-H₂-Air mixtures. Equivalence ratio for CH₄ mixtures is found to be within different range from traditional self-ignition combustion
