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. ... En savoir plus
FEM Simulation of Generation of Bulk Acoustic Waves and their Effects in SAW Devices
This paper presents finite element method (FEM) simulation study of the generation of bulk acoustic waves (BAWs) and their effect on the performance of surface acoustic wave (SAW) devices, using COMSOL Multiphysics. A SAW delay line structure using YZ-cut lithium niobate substrate is ... En savoir plus
Air Gap Field Analysis of Single Sided Linear Induction Motor With Time-Harmonic Finite Element Method
In recent years, the single-sided linear induction motor (SLIM) has been the most suitable choice for electric vehicles of the wheel and touchless type. The reason is simplicity in manufacturing, capability in applying direct force, moving and braking and low pollution. To study the ... En savoir plus
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 ... En savoir plus
Determination of Electric Potential Distribution and Cell Resistance of a Uranium Electrorefining Cell
Electrorefining is an electrolytic process for obtaining high purity metal. In this process the impure metal is made anode and the high purity metal is deposited on cathode. Electrorefining is a key step in pyrochemical reprocessing of spent fuel from metal fuel fast reactors. ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ...
