The high temperature measurement of thermal conductivity is vital for predicting nuclear fuel performance both during reactor operation and accident conditions. The proposed method uses experimental thermograms obtained via high temperature laser-flash heating of a disc-shaped sample in combination with finite element analysis and parameter optimization to calculate the thermal conductivity ...

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes place. The temperature of the material during the reaction is one of the most influencing parameter and has to ...

The majority of elderly patients are subjected to hip bone replacement due to dislocation of bone, mechanical failure and infection. The life time of the implant varies from patient to patient depending on their daily physical activity. Once the implant fails, re-operation of hip bone replacement is performed. In United States, there are approximately 18 revision hip replacements performed for ...

Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, reducing stress on power generation infrastructure. Batteries firm the output capacity of intermittent wind ...

INTRODUCTION: Point of care diagnostics aimed at low-resource settings need to be relatively simple, robust and low-cost. The most commonly-used diagnostic platform in these settings is the lateral flow assay (LFA). LFAs are paper-based immunoassays designed to perform on-strip binding with analytes in patient samples in order to generate a visual signal if disease-specific antigen is ...

The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic machines. Nonlinearities due to the high level of acoustic pressure generate DC flows that are superimposed on the ...

In the molding industry, high productivity rate, low energy consumption, large 3D parts, and homogeneous temperature distribution are the main targets. The 3iTech® inductive technology developed by RocTool ensures both good temperature homogeneity and short heating time. Conventionally, to guarantee efficient cooling, a turbulent water flow is directly integrated into the mold. Ideally, to cope ...

A solidification process of casting explosives in shell is studied in this paper. An enthalpy method approach is used to model the solidification process. Both the thermal and mechanical effects are taken into account. An ALE (Arbitrary Lagrangian-Eulerian) method is used to represent the physical deformation due to solidification. Results from the model are verified against experimental ...

The hot stamping of boron steels for producing complex structural components of the car body-in-white is more and more widespread. Optimization of sheet forming technologies at elevated temperatures is still troublesome, since the thermal, mechanical and metallurgical phenomena interacting during hot stamping force to feed the numerical model of the process by a huge amount of data, most of ...

A new type of MRI compatible intracranial electrode based on Polymer Thick Film (PTF) is presented and studied using COMSOL Multiphysics. The geometry considered was a two-dimensional cross section cut of 5 mm thick electrodes with 5 cm leads on top of a 2×10 cm slab representing Gelfilm, or the substrate. The resistive leads were compared with metallic leads to estimate the ...
