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 ...

The main object of this paper is the determination of the impulse response, in the low frequency range, for calculating the reverberation time and the energetic parameters in this space. An absorbing material is modelled by using the propagation of sound waves in an equivalent fluid. The results of this Finite Element model are compared with experimental measurements of impulse responses ...

In this paper we study the natural convection for Dual In-Line Memory Module (DIMM) systems. Numerical models are developed using COMSOL Multiphysics. The results, obtained for imposed ambient temperature and operative conditions (power supplied to the CPUs) were produced and complex fluid motion field could be detected.

The complete coupling among the Incompressible Navier-Stokes - General Heat Transfer -ALE modes can be a reliable tool for the simulation of the plastic deformation process. This is shown here.
