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 ...

REBCO tapes belong to a class of high-temperature superconductors (HTS) that can be superconducting at liquid nitrogen temperatures (77K) as opposed to typical superconductors such as Nb3Sn which need to operate at liquid helium temperatures (4K). One important aspect of designing a super conducting coil is the ability to predict the critical current above which the conductor becomes ...

Two different Finite Element Method (FEM) models of the CANDU® nuclear fuel channels were compared against experimental data to determine if the curvature of the fuel channels is necessary to consider for measurements of the pressure tube to calandria tube gap. The different models were compared against experimental measurements under variations in the wall thickness of the pressure tube. For ...

The lamination of substrates with thin coatings is commonly used in furniture, automotive and avionic industries. In the lamination process the hot melt adhesives are widely used and typically activated at temperatures from 80°C to 140°C by resistive heating. This requires a heat transfer through the coating and/or the substrate. To make the process more flexible, to decrease its energy ...

This paper is an investigation into the effect of blood vessel movement on measurement accuracy of blood flow rate using magnetic flow meters. The investigation used a Finite Element model of the magnetic flowmeter built using COMSOL Multiphysics® software by integrating the modules of laminar fluid (blood) flow, electric and magnetic field and structural dynamics (FSI), to mimic performance of ...

Two-generation superconducting coils carrying large current in alternating magnetic fields is very common in electrical applications such as HTS linear motor. So it is meaningful to study the characteristics of coated superconductors in the presence of travelling magnetic field. In this paper, by using the finite element simulation software COMSOL Multiphysics® software, the characteristics of ...

This elaboration presents a pre-study on automatic rotor construction for the flywheel energy storage system dedicated to operate in the levitation mode. The optimization profile model is used as a basic profile source. The 3D flywheel shape is generated on the base of obtained profiles. Eigenfrequencies are calculated to validate the operation on rigid mode. A steel and aluminum based ...

A wireless passive pressure sensor and the measurement system were design and simulated using COMSOL 4.3. The sensor is based on MEMS capacitor attached to a planar inductor for wireless powering and readout. An external coil is used for the measuring system. The pressure to be measured compresses the MEMS capacitor and changes sensor\'s resonance frequency. COMSOL 4.3 was used for the analysis ...

After spinal cord injury (SCI) the functions of the lower urinary tract are often disrupted and may have fatal consequences for the patient. It has been shown that using a transrectal probe developed by Craggs et al., through conditional transrectal stimulation of pudendal nerve, it is possible to treat hyperreflexia in some of the SCI patients. To maximise the efficacy of this type of ...
