Abstract
A new capability is developed that enables the modeling of hydrocarbon fuel reforming for certain reactor geometries. The system described in this paper considers a shell-and-tube configuration for which the catalytic reforming chemistry is confined within the tubes. The models are designed to accommodate detailed gas-phase and catalytic reaction kinetics, possibly including hundreds of species and thousands of reactions. The shell flow can be geometrically complex, but does not involve any complex chemistry. An iterative coupling algorithm is developed with which the geometrically complex flow is modeled with FLUENT and the chemically complex reforming is confined to straight tubes. The paper illustrates the model using propane partial oxidation and reforming as an example.
