abstract

Numerical modeling of methane-steam reforming is performed in a mini/microchannel with heat input through Nickel-deposited channel walls. The low-Mach number, variable density Navier-Stokes equations together with multicomponent reactions are solved using a parallel numerical framework. Methane-steam reforming is modeled by three reduced-order reactions occurring on the reactor walls. The surface reactions in the presence of Nickel catalyst are modeled as Neumann boundary conditions to the governing equations. Effects of the total heat input, heat flux profile, and inlet methane-steam molar concentration on production of hydrogen are investigated in detail.
