The paper presents a two-dimensional model to describe the gas flow in a propane autothermal reactor, developed at the CNR-ITAE Institute, and aimed to design a Beta 5 kWe hydrogen generator, named HYGen II, to be used with Polymer Electrolyte Fuel Cells (PEFCs) for residential applications. The main aim of the mathematical model was to optimize the reactor geometrical key parameters (diameter ...

Heat and mass transfer can be analyzed for conditions that may limit shelf-life. With this target, the purpose of the present work is the development of a general model which is applicable to a large variety of packaging configurations, food products and environmental conditions. To this end, COMSOL Multiphysics is exploited in a full 3D geometry.
