We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module (general form) and solves Maxwell equations using a highly non-linear resistivity to describe the superconductor ...

This paper will discuss the comprehensive solution adopted for converting the 3D digital/medical images directly into the computational model. The workflow using Simpleware Software – ScanIP and + ScanFE – will be illustrated including the option for directly exporting fully compatible models to COMSOL Multiphysics. The extra functionality that allows introduction, positioning and ...

Thermal ablation of malignant tumors has been conducted in patients who are not candidates for surgery for more than ten years. Recently it has been shown that low energy DC pulses can cause cell necrosis. An undesirable characteristic of DC pulses in-vivo is the stimulation of skeletal muscle. The intensity of the contraction depends in part on the duration and height of the pulse. Through the ...

Signal processing algorithms for chemical sensing/monitoring have been subject of considerable research interest in the recent years mainly due to their diverse applicability. When the concentration of chemical agent is small, the dispersion of particles is governed by stochastic differential equations describing more complex motion mechanisms such as Brownian motion. In this paper we propose ...

This paper presents the solution of a transient electromagnetic problem using COMSOL Multiphysics. The paper also presents a closed-form solution of a transient electromagnetic dipole. The computational solution compares well with a closed-form solution for this problem. This work implements Maxwell’s equations in the RF module and optimizes solver parameter settings to resolve the transient ...

COMSOL Multiphysics is a powerful tool in theoretical study. Lei Zhou, Jiping Huang and other professors in Physics Department, Fudan University have achieved some exciting results of soft, tunable metamaterials. We use it to study non-equilibrium behavior of rhoeological (ER) fluids and polar molecule dominated rheological (PM-ER) fluids. Numerical solutions using the Onsager’s principle would ...

The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number of prototype builds, and post-build problem avoidance for physical prototypes and production products. ...

A successful development of an effective quench detection and protection method for a high temperature superconducting (HTS) coil based on a HTS coated conductor tape lays on a thorough understanding of its slowly propagating, three-dimension (3D) quench behavior. Toward this goal, a 3D micrometer scale finite element (FE) thermo-magnetostatic HTS tape model is developed and implemented in ...

We propose the study of an electronic sensor allowing the collection of sprays in free space. The detector consists of three elements: a photodiode situated in the center of the structure to which is applied a bias voltage, an aluminum ring which referenced to a voltage higher than that of the photodiode and an insulating material disk (polyvinyl chloride). The total size of the structure is ...
