The problem of storage, and release of thermal energy is an important challenge in various industrial fields. Several systems for thermal energy storage exist like phase change materials (PCM) and thermochemical storage . The first system usually addresses short term storage (day duration) while thermochemical storage are very interesting for longer duration (seasonal storage). However, ...

This computational implementation presents a new strategy of coupling two 3D models to satisfy the requirements of the comprehensive model of a unitary Proton Exchange Membrane fuel cell, including its internal geometries and constitutive materials, as well as distinct physical and chemical processes. Those different simultaneous processes required computational effort and the solution was the ...

Catalytic fast pyrolysis is a process by which biomass may be converted into liquid hydrocarbon transportation fuels and chemical co-products that are alternative to their petroleum-derived counterparts. Chemical compounds in raw pyrolysis vapor have high oxygen content and therefore must be deoxygenated in order to meet specifications for hydrocarbon fuels. One strategy to accomplish this is ...

The ear doesn’t solely listen but it also speaks. Sounds formed in the inner ear which are measurable in the outer ear are called Otoacoustic emissions (OAEs). Some claim these are produced by the outer hair cells (OHCs), the amplifiers in the inner ear. Our hypothesis is that the OHCs only amplify distortion products (DPs) but do not produce them.

In inductive heating simulations the electromagnetic properties of the steel have a significant impact on the temperature pattern along the heated product. Indeed, taking into account the non-linearity of the ferromagnetic material properties is a key point to have relevant simulation results. In particular, it is important to correctly include the nonlinear relationship between the magnetic ...

Landfill is currently the most dominating method to dispose wastes, which are caused by the lives of residents and constructions of cities and towns. Because of large amounts of organic substances in landfills, they will undergo continuous microbial degradation, which generates a lot of landfill gas. The gas consists mainly of CH4, CO2, O2 and N2, and it is also a promising source of renewable ...

During the last decades, mid-IR (3-12µm) laser sources have attracted attention due to their potential applications in different fields like infrared counter-measures (e.g: missile jamming) and remote chemical sensing. In this context, Onera has been working on the development of non-oxid materials and still is developing new crystals that allow to reach higher power and to extend the ...

As in industrial countries, people spend most of their time indoors and the stringent heat-insulation measures in combination with deficient ventilation have a negative impact on indoor air quality, one approach for abating indoor air pollution is the integration or retrofitting of a photocatalytic oxidation or PCO reactor into continuous flow. PCO technology is very cost-effective, efficient ...

COMSOL Multiphysics® is used to simulate thermal flow experiments at out University for Applied Physics. Students have to measure thermal flow problems and verify the measurements with detailed simulations. The desired accuracy is 5% or less. The presentation will cover 3 laboratory experiments: cooling of an Aluminum rod by natural convection, time dependent heat flow into a container with sand ...

Particle accelerator technology evolves gradually towards improving reliability and efficiency of the accelerator machines, which would reduce their cost for current applications and even make them more accessible to new industrial applications. RF cavities are utilized in particle accelerator machines to propel the particle beam by properly coupling the energy from RF sources to the particle ...
