In this study, the effect of the levels of hydrogen addition to methane-air premixed flame in a micro-stepped reactor has been studied numerically. In addition, the effects of mixture velocity and walls’ thermal conductivity (Kw) on the flame’s location, temperature, and species distribution in a micro reactor were calculated using a 2D numerical laminar steady code. The results ...

we optimized the geometries of the graphene and graphene with hydrogen using pw91vwn, pwcipl,mpwlyp, g96lyp, g96141.0-210.6-310, 6-31g*ievels of theory and compared our results with each other.we present the most important structural parameters determined for the addition of a hydrogen atom tographene and the outward movement of the carbon atom that is bonded to hydrogen is 0.48 a also wecalcul...
