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 ... Read More

Heat Transfers and Solid Mechanics in Microarchitectured Materials Using Periodic Homogenization

F. Viry1, J.-D. Wheeler1, P. Namy1
1SIMTEC, Grenoble (France)

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. ... Read More

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 ... Read More

Investigation of the Electric Conductivity of an Electrically Heated Reactor

C. Geitner1
1Fraunhofer-Institut für Umwelt-, Sicherheits- und Energietechnik UMSICHT, Oberhausen, NRW, Germany

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 ... Read More

Investigations on Talik Formation During Changes to Cold Climates

K.-P. Kröhn1
1GRS gGmbH, Braunscheig, Germany

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 ... Read More

Methanation in Catalytic Reactor

M. Schopfer1, C. Nkoumou1, D. Martinet1, C. Ellert1
1University of Applied Sciences Western Switzerland (HES-SO Valais-Wallis), Sion, Valais, Switzerland

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 ... Read More
