Sulfur Deactivation Effects on Catalytic Steam Reforming of Methane Produced by Biomass Gasification

P. Sadooghi[1], R. Rauch[1]
[1]Vienna University of Technology, Vienna, Austria

Sulfur, which is incorporated in the biomass structure, is released into the product gas during gasification as hydrogen sulfide. Hydrogen sulfide is known to deactivate nickel based steam reforming catalysts by chemisorption on the metal surface during steam reforming process. ... Read More

Structural Analysis of a Pressure Sensor for High Temperature Environments

S.V. De Guido[1], G.S. Masi[1], P. Vladimirovich Miodushevsky[1], L. Vasanelli[1]
[1]Department of Innovation Engineering, University of Salento, Lecce, Italy

Pressure sensors operating at the temperature higher that 500 °C are absent in the world market. Our goal is to develop a pressure sensor that can operate at the high temperature up to 700 °C. Our sensor will be made up of a ceramic sensible element and a metallic case. The sensible ... Read More

A Theoretical Model for the Control of Color Degradation and Microbial Spoilage Occurring in Food Convective Drying

S. Curcio[1], M. Aversa[1]
[1]University of Calabria, Department of Engineering Modeling, Rende, Cosenza, Italy

The aim of this work was the development of a predictive model aimed at identifying a proper control strategy of food drying process. In particular, it was intended to determine the effect of operating conditions both on the color degradation, chosen as a reference quality parameter, and ... Read More

Multiphysics Process Simulation of Static Magnetic Fields in High Power Laser Beam Welding of Aluminum

M. Bachmann[1], V. Avilov[1], A. Gumenyuk[1], M. Rethmeier[1]
[1]BAM Federal Institute for Materials Research and Testing, Berlin, Germany

The article deals with the application of the Hartmann effect in high power laser beam welding of aluminum. The movement of liquid metal in a magnetic field causes electric currents which build a Lorentz force that decelerates the original flow. The numerical model calculates the ... Read More

Optimal Placement of Piezoelectric Plates to Control Multimode Vibrations of Rotating Beam

F. Botta[1], D. Dini[2], S. Gentili[1], G. Cerri[1]
[1]Dipartimento di Ingegneria Meccanica e Industriale, Università degli Studi di Roma Tre, Roma, Italy
[2]Department of Mechanical Engineering, Imperial College London, London, United Kingdom

Turbomachines blades are forced by a load resulting from the interaction with the fluid. The consequent vibrations, and the associated fatigue phenomena, can give catastrophic failures and the reduction of the blades life. It could be increased if damping system are used. The ... Read More

An Integrated Numerical-Experimental Approach for Heat Transfer Analysis of Industrial Furnaces

G. Petrone[1], A. Adorisio[2], S. Adorisio[2], M. Calderisi[3], A. Cecchi[3], M. Scionti[1], F. Turchi[3]
[1]BE CAE & Test, Catania, Italy
[2]Gadda Industrie, Ivrea, Italy
[3]Laboratori Archa, Pisa, Italy

This paper deals with an integrated numerical and experimental analysis work aiming at the investigation of the thermal distribution inside an industrial furnace built for metal materials treatments. The main goal of the research is to find the geometrical and/or functional parameters ... Read More

High Frequency Electromagnetic Device Modeling with COMSOL: Simulation vs. Experiment

P. Alotto[1], F. Dughiero[1], F. Bressan[1], M. Bullo[1]
[1]Università di Padova, Dipartimento di Ingegneria Industriale, Padova, Italy

Computer simulation is mandatory for the optimization of electromagnetic devices. Here we concentrate on two classes of devices operating in the MHz and GHz range, namely microwave ovens and TEM cells for electromagnetic compatibility testing. In particular we concentrate on the issue ... Read More

Pore-Scale Simulation of Two-Phase Flow with Heat Transfer Through Dual-Permeability Porous Medium
