Numerical Modeling Of Thin Superconducting Tapes
Second-generation high-temperature superconducting (HTS) tapes are very promising superconductors for ac applications and numerical models are very important for predicting their performance, e.g. for computing the ac losses. These tapes are characterized by a very large aspect ratio: ... 詳細を見る
FEM-Investigations Of Superconductor/Ferromagnet Heterostructures: A Compliance Test Between Various Models
In recent years, a number of numerical and finite-element-methods in particular - some implemented in COMSOL - have been developed to investigate various properties of superconducting materials. Following converse conclusions by different models regarding similar physical phenomena, the ... 詳細を見る
A General Method for Solving Equations - The Dynamical Functional Particle Method
Given any equation L(u)=0, e.g. a partial differential equation, it can be considered to be the stationary solution of a time dependent equation (in fact, time need only to be fictitious time not real time). Our approach is to choose the time dependence in analogy with an oscillating ... 詳細を見る
COMSOL Implementation for Upscaling of Two-Phase Immiscible Flows in Communicating Layered Reservoirs
Waterflooding is widely used in secondary oil recovery. The physics is described by the model of two-phase flow in porous media. The aim of the present work is to implement this model in COMSOL Multiphysics and to simulate the process of waterflooding. It is analyzed in two dimensions. ... 詳細を見る
Powerful automation and optimization methods for Material- and Process analysis with COMSOL Multiphysics and Matlab
Thomas Frommelt received his PhD in physics in 2007 from the University of Augsburg for experimental work and simulation analysis on acoustically driven microfluidic mixing. In 2008, he joined the SGL Group and introduced COMSOL Multiphysics as the tool for flexible equation based ... 詳細を見る
Design Of A Flat Membrane Module For Fouling And Permselectivity Studies
Flat membrane modules are widely used to study the membrane performance at the laboratory which is influenced by pressure and velocity. Most modules designed for laboratory studies have high pressure drop and abrupt changes of flow direction what yield to lack of uniform flow and ... 詳細を見る
Robust and Reliability-based Design Optimization of Electromagnetic Actuators Using Heterogeneous Modeling with COMSOL Multiphysics and Dynamic Network Models
For an exemplary electromagnetic actuator used to drive a Braille printer, a design optimization was performed. The optimization involves stochastic variables and comprises nominal optimization, robustness analysis and robust design optimization. A heterogeneous model simulates the ... 詳細を見る
Fluid Flow Simulations Using New CFD Module
COMSOL\'s new CFD Module has been tested for laminar and turbulent flows in simple geometries, with couple or segregated solver. These tests allow mesh sensitivities and comparison with analytical solutions. They also give a first idea of cpu time and RAM use for standard cases. In a ... 詳細を見る
A Flexible Scheme For Numerical Homogenisation In Linear Elasticity
Musculoskeletal mineralised tissues (MMTs), like bone or tendon, are a prime example of naturally occuring, hierarchically structured material. They display a great variety in mechanical function but are all based on essentially the same building block: the mineralised collagen fibril ... 詳細を見る
Wind Evaporation On Wetted Surfaces Under Uncertainty Conditions
Brine disposal from desalination plants placed in inland areas far from sea is an important problem. Evaporation ponds can be used for reducing the waste to solid state but they require huge amounts of land. Evaporation using arrays of wet surfaces can minimize the land requirements. One ... 詳細を見る
