Validation of Space Charge Laminar Flow in Diodes
The well known Pierce design of electron and ion diodes is the base of particle source extraction systems [1,2]. It was heavily studied up to 1960 with analog computing and it now offers us a known case against which to compare the precision of fluid and particle tracing codes. The ideal ... 詳細を見る
A Parametric Study of Shock Wave Simulations with Help of COMSOL Multiphysics
Adiabatic compression of gases can work as an ignition source and is still one of the main causes of accidents in chemical plants processing tetrafluoroethylene (Reza and Christiansen, 2007). The ignition of tetrafluoroethylene induced by adiabatic compression has been studied ... 詳細を見る
Evaluation of Low-Cycle-Fatigue Life of Solder Joints in Surface Mounting Power Devices by Finite Element Modeling
The reliability of solder joints [1,2] is one of the key factors in the determination of the reliability of the high power density electronic converters, being the solder joints both the mechanical, the electrical, and often the thermal connections between the electronic component and ... 詳細を見る
Turbulent Bounded Flows for Oil & Gas Industry with COMSOL CFD Module
Industrial applications of fluid mechanics can require to satisfy necessities as diverse as legal norms, optimization requirements and manufacturing constraints. Therefore a Computational Fluid Mechanics software often becomes a must in the development of new devices or the improvement ... 詳細を見る
Sulfur Deactivation Effects on Catalytic Steam Reforming of Methane Produced by Biomass Gasification
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. ... 詳細を見る
Structural Analysis of a Pressure Sensor for High Temperature Environments
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 ... 詳細を見る
A Theoretical Model for the Control of Color Degradation and Microbial Spoilage Occurring in Food Convective Drying
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 ... 詳細を見る
Multiphysics Process Simulation of Static Magnetic Fields in High Power Laser Beam Welding of Aluminum
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 ... 詳細を見る
Optimal Placement of Piezoelectric Plates to Control Multimode Vibrations of Rotating Beam
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 ... 詳細を見る
An Integrated Numerical-Experimental Approach for Heat Transfer Analysis of Industrial Furnaces
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 ... 詳細を見る
