This paper deals with a numerical modelling technique based on finite elements method for computing magnetic field and current density distributions in high temperature Superconducting (HTS) tapes. The model is developed using the T-ῼ formulation for which the degree of freedom (DOF) and the CPU time decreased considerably in AC losses analysis, and it is also observe that T-ῼ formulation give ...

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to investigate the feasibility of the underwater application of the directional sensor based on the hearing ...

A photoelectrochemical (PEC) cell uses solar energy to split water to hydrogen and oxygen in single integrated device. Electrochemical impedance spectroscopy is a suitable tool to characterize recombination and reaction mechanisms in PEC cell. Full numerical drift-diffusion calculations of the electrochemical impedance were conducted. The linear dependence of abscissa (real part) in Nyquist ...

The finite element method was used for simulating the dielectric response of polymer matrix dielectric composites with randomly and evenly distributed fillers. The dielectric simulation of the composite materials was conducted using a time harmonic-electric current solver in the AC/DC Module of the COMSOL Multiphysics® software. The calculations were performed for a wide range of filler contents ...

One of the limitations of pipelines performance and structural integrity assessment is the continuous inspection of possible leaks due to corrosion or other types of failure mechanisms. Efforts to develop new technologies started several decades ago where different inspection techniques were used to enhance pipelines structural integrity. However, although available technologies present some ...

This paper studies oxide forming on titanium, during cold gas dynamic spraying with air. This is a quite new spraying method, which can be used to spray material having high affinity for oxygen. The model allows for the diffusion of oxygen through the oxide layer, reaction on the oxide-titanium interface and expansion of oxide, due to difference in molar density. It was implemented in COMSOL ...

COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the resulting interfacial thermal stresses. Experimental data from the raw materials are implemented in the model ...

A 3D electro-conjugate heat transfer model was made to study an embedded microfluidic/TEG system (μF/TEG) system. An innovative embedded microfluidic/TEG system (μF/TEG) system is proposed which enables a device to be able to provide power to its cooling system eliminating external power input and resulting in energy efficient and more reliable heat removal system. The research identifies ...
