Electrochemical Impedance Spectroscopy for the on-board diagnosis of PEMFC via on-line identification of Equivalent Circuit Model parameters
(2014-04-04)
Proton Exchange Membrane, also named Polymer Electrolyte Membrane fuel cells (PEMFC) are
interesting devices for energy conversion. Their development is due to the high efficiency,
acceptable power density, quick start-up ...
Development of a model-based diagnosis algorithm oriented towards solid oxide fuel cell systems: approach and application
(2014-07-07)
The present dissertation illustrates the complete procedure of developing a model-based
diagnosis algorithm and shows its application to a pre-commercial Solid Oxide Fuel Cell (SOFC)
system. The main motivations of this ...

Stabilità di flussi in cavità aperte
(2014-09-12)
Negli ultimi venti anni il costo dei carburanti ha subito un notevole aumento con un significativo impatto sui costi del trasporto aeronautico. Inoltre, la Comunità Europea ha lanciato una politica di salvaguardia dell’ambiente ...
Advances in lubrication technology and modelling. Novel nanoscale friction modifiers - Piezoviscosity effect in EHL contacts
(2014-06-22)
Lubricant additives have an important influence on the lubrication performances. These additives are active ingredients which can be added during a blending process to base oils in order either to enhance the existing ...
Receptivity in transition prediction
(2014-09-12)
The laminar-turbulent transition is a complex phenomenon involved in
several multidisciplinary design issues, such as skin friction drag reduction,
anti-icing and de-icing system performance prediction and heat transfer ...
Experimental and numerical characterization of heating domestic appliances for energetic efficiency improvement
(2014-12-13)
Every year 5 million of boilers for domestic heating are sold in the European Union (EU). Because heating contributes to more than 20% to the whole energy use in the EU strategies for energy saving are of great interest.
Currently ...
