Multilayer planar transformers are widely implemented in power electronic applications. The design process of these elements is complicated due to the complexity of a magnetic circuit and high frequency interactions between windings. Additionally, an analytical approach to the analysis (based on mathematical formulas) can be uncertain. The applied FEM method of the analysis can be a solution to ...
Exploratory FEM-Based Multiphysics Oxygen Transport and Cell Viability Models for Isolated Pancreatic Islets
Diabetes Research Institute and the Department of Molecular and Cellular Pharmacology, University of Miami, Miller School of Medicine, Miami, FL, USA
Cellular-level oxygen consumption and cell viability models incorporating physiologically realistic assumptions and fully scaled 2D/3D geometries have been implemented in COMSOL Multiphysics for isolated pancreatic islets. Oxygen consumption was assumed to follow Michaelis-Menten–type kinetics and to cease when local concentrations fell below a critical threshold. Results are in good agreement ...

MEMS gyroscope technology provides cost- effective method for improving directional estimation and overall accuracy in the navigation systems. This paper presents a tuning- fork gyroscope (TFG)  with a perforated proof mass. The perforated proof mass used in the design enables the reduction of the damping effect. This MEMS based gyroscope was designed using COMSOL Multiphysics 4.2a. This ...

Introduction Fluid flow patterns in research or process-scale equipment where a fluid is contained between concentric rotating cylinders in the absence of bulk axial flow has received notable attention in the field of fluid mechanics. Annular flows occur in many practical applications, such as in the production of oil and gas, fluid viscometers, centrifugally-driven separation processes, ...
Modeling of Ultrasonic Transducers and Ultrasonic Wave Propagation for Commercial Applications Using Finite Elements with Experimental Visualization of Waves for Validation - new

Cambridge Ultrasonics, Over, UK
Finite element (FE) modelling of ultrasonic propagation using COMSOL Multiphysics® simulations can be used to create images of waves. Unfortunately, in time-stepping solutions, it is possible for numerical instabilities to grow large and dominate the solution adversely. Any design of transducer that is based upon poorly-configured FE models is unlikely to perform as expected and will almost ...

Chemical vapor deposition is considered a promising method for synthesis of graphene films on different types of substrate utilizing transition metals such as Ni. However, synthesizing a single-layer graphene and controlling the quality of the graphene CVD film on Ni are very challenging due to the multiplicity of the CVD growth conditions. COMSOL Multiphysics® software is used to investigate ...

Our goal is to reproduce the key features of carangiform swimming by running 2D simulations which fully exploit the Fluid-Structure Interaction interface of COMSOL Multiphysics software. Fish swimming is an important area of research, with relevant developments on biomechanics, robotics and mathematical modeling. Usually, in fish swimming simulations, the motion of the fish is assigned, and much ...

A one-dimensional model of Excimer Laser-Annealing of amorphous silicon layers which are irradiated with a KrF excimer laser is described. For realisation, the application mode heat transfer in solids is used. The model predicts a melt threshold for the energy density of the laser of 88.5 mJ/cm^2. It also predicts a linear increase of the melt duration with a slope of approximately 625 (ns*cm^2) ...

At the forefront of a new generation of sensors graphene and graphene composite materials are intensively studied for medical and biosensing applications. The outstanding electrical, mechanical and quantum properties of graphene make them a promising material solution to overlap the existing gap between biological and non-biological systems into a continuum like-viscoelastic integrated model. ...
