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 ...

This paper describes an example of full fluid structure interaction. The 2D dynamics of a box-type pile-anchored floating breakwater is solved by means of two models using COMSOL Multiphysics . Simulated wave transmission and vertical displacements of the floating breakwater agree well with physical model results.

The understanding of the distribution of electrostatic forces at the nanoscale is of fundamental importance for the development of nanotechnology. In this work, in order to quantify the EFM cantilever/tip-sample interaction, we present a 3D static Finite Element Analysis of the electromechanical interaction between conductive probes and samples, using COMSOL Multiphysics. The simulation ...

Microcantilevers made of crystal silicon are probably the most diffused type of MEMS because of their simple fabrication and their vast applications. In this presentation we treat the mechanical behaviour of silicon mirocantilevers, and also give an overview of the many application areas that these apply to.

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.

In the present paper we report the results obtained applying COMSOL Multiphysics to the numerical simulation of Cyclic Voltammetries (CV’s) at microelecrodes arrays. CV’s at inlaid micro disk electrode arrays have been simulated showing how the electrochemical response is affected by geometrical parameters such as the electrode radius and the distance among the electrode canters.
