The microwave heating and processing of heterogeneous material is usually simulated using a set of coupled PDE equations in an homogeneous medium. Nowadays it is possible to describe more accurately the process with a suitable description of the heterogeneities that is at the grain ... 詳細を見る

In this paper, thermal properties of composites are investigated numerically and experimentally. In the numerical study, finite-elements method in COMSOL is used to modelize heat transfer and to calculate the Effective Thermal Conductivity (ETC) of the composite for three elementary ... 詳細を見る

The freezing curve of the food material was extracted from Differential Scanning Calorimetry experiments. A heat conductive model was generated in COMSOL, including the thermo-physical characteristics and the phase transition behavior. The resulting temperature-time evolutions at ... 詳細を見る

Finite element modeling of agricultural materials is very often used for describing physical processes. However, exact physical measurements are needed as input parameters for the models. Knowing the driving forces (potentials) during heat and mass transfers is necessary for an accurate ... 詳細を見る

Non aqueous metal fuel reprocessing involves electrochemical deposition of spent metallic fuel on the cathode of an electrolytic cell. Apart from metal fuel, the cathode deposit would also contain occluded molten salts and liquid cathode. Subsequent purification and consolidation of ... 詳細を見る

Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale ... 詳細を見る
