Outer wall surface temperature data for catalytically supported thermal combustion systems with extremely high gas flow rates

At the inlet, a fixed, flat velocity profile is used. This boundary condition fixes the convective component of the flux of species and energy, but the diffusive component depends on the gradient of the computed temperature or species fields. Symmetry boundary conditions are applied at the centerline between the two plates. At the exit, a fixed pressure is specified and far-field conditions are imposed for the rest of the variables. At the interface between the wall and the fluid, no-slip boundary condition is employed. The heat flux at the wall-fluid interface is computed using Fourier's law and continuity in temperature and heat flux links the fluid and solid phases. The left and right edges of the wall are assumed to be insulated. Newton's law of cooling is used at the outer edge of the wall. All internal heat transfer between the fluid and the wall is calculated by accounting explicitly for the convective and conductive heat transport in the model within the fluid and within the wall. The wall thermal conductivity is taken as an independent parameter to understand how important thermal management is. The mathematical formalism developed to describe transport phenomena and chemical kinetics is implemented into ANSYS FLUENT. The computer code and its usage are fully documented. More specifically, ANSYS FLUENT is applied to define the terms in the equations relating to conservation, thermodynamics, chemical production rates, and equation of state, and then combine the results to define the problem involving surface chemistry. To describe the surface reaction mechanisms in symbolic form, the following information is required, including the thermochemical properties of surface species in the surface phases, names of the surface species, site densities, names of all surface phases, Arrhenius rate coefficients, reaction descriptions, and any optional coverage parameters.
