Finite Element Analysis of Friction Stir Welding of Al Alloy and Inconel 718
Friction Stir Welding (FSW) is a solid-state joining technique that has become increasingly popular and efficient for welding both similar and dissimilar metallic materials. Despite its success in joining dissimilar materials, further development is necessary to meet industry ... En savoir plus
Heat Exchange Mechanisms in Energy Quay Walls: Field Observations and Numerical Analysis
The increasing demand for energy and the need to reduce reliance on fossil fuels in response to climate change have spurred the exploration of renewable energy sources. Energy Geostructures address these issues by providing at the same time mechanical support to overlying structures and ... En savoir plus
Heat Transfers and Solid Mechanics in Microarchitectured Materials Using Periodic Homogenization
Microarchitectured materials are generally made of different compounds bound at the microscopic level using a periodic pattern. This results in a macroscopic material with new properties arising from each of the individual compound properties and the way the microarchitecture binds them. ... En savoir plus

Indoor Thermal Analysis of a Storehouse
The aim of this study is to evaluate the airflow thermal distribution inside a storehouse in different operational conditions. A warehouse of 12,600 m3 in volume is considered for fluid-dynamical and thermal analysis. Coupled Navier-Stokes and energy equations are solved considering or ... En savoir plus
Influence of Materials and Packaging Solutions on Thermal Behaviour of Power Modules
Nowadays, designing ever more efficient power modules requires complex materials and more innovative methodologies. To significantly reduce the lead time of the devices and decrease the costs, especially during the prototyping and the testing phases, a Finite Element Analysis (FEA) can ... En savoir plus
Investigation of the Electric Conductivity of an Electrically Heated Reactor
An electrically heated fixed bed (19 mm diameter, 200 mm length) is investigated regarding its electrical conductivity. Various electrically conductive activated carbons are used. The fixed bed is constructed from activated carbon pellets and/or activated carbon fabric. Electrical ... En savoir plus
Investigations on Talik Formation During Changes to Cold Climates
Over the past million years, several cold ages have occurred and thereby caused perma-frost conditions basically all over the present area of Germany. Since in Germany the safe-ty of a nuclear waste repository legally needs to be investigated for a period of one million years, the ground ... En savoir plus
Methanation in Catalytic Reactor
Power-to-gas is an important area of research for reducing greenhouse gases and seasonal energy storage. Methane, with a Lower Heating Value of 50 MJ/kg, is already a commonly used gas, and its synthesis using green hydrogen production (electrolysis of renewable energy) is a remarkable ...
