Pore-scale modeling of multiphase flow through porous media is addressed most frequently to improve our understanding of flow and transport phenomena in such settings. It can be used to obtain macro-scale constitutive equations, to assign multiphase flow properties in large scale models, to predict how these properties may vary with rock type, wettability, etc. The description of a physical ...

Transformers, as any other industrial products, have to comply with various requirements on noise levels. Three main sources of noise can be identified in transformers: no-load noise or core noise generated by magnetostriction in the core steel laminations, load noise produced by electromagnetic forces in the windings and noise due to auxiliary equipment such as fans and pumps used in the cooling ...

There are various alternative options concerning modeling fluid flow within fractures in porous media. We give a general overview, with remarks concerning the modeling using COMSOL Multiphysics. Moreover we define and study two test cases for intercomparison. Finally for one of the testcases some results of an extensive sensitivity study is presented.
Using Computational Fluid Dynamics Model to Predict Changes in Velocity properties in Stented Carotid Artery

Atherosclerosis is a disease that narrows, thickens, hardens and restructures a blood vessel due to substantial plaque deposit. In the Carotid Artery, the decision to treat using endarterectomy and stenting is determined by the velocity as measured by Doppler flow in the common Carotid Artery. The measured Doppler velocity as compared with the contra-lateral side has been correlated with the ...

Instrumented indentation is increasingly used as an alternative non-destructive test method to measure mechanical properties of small volumes of materials. In this work, the instrumented indentation test is applied as a non-destructive method to assess the mechanical properties of TiAl components during the setup of a real production process. This study is a preliminary contribution devoted to ...

This paper presents preliminary estimations of CO2 overpressure into the reservoir and CO2 leakage through the caprock and the overburden. A simple, two-phase flow model in porous media based on Darcy’s law was used, in order to explore easily long time periods. The models produced by COMSOL Multiphysics allow sensitivity studies and preliminary evaluations of the relations between CO2 leakage ...

In order to investigate the implantation of microprobes into brain tissue, we developed a finite-element and a physical model to replace real biological tissue for mechanical testing. Penetrating forces of a tungsten indenter into a layered structure was investigated with different indentation speeds. Numerical and physical model are in good correspondence to each other and reproduce measured ...

We present a full modal -analysis of optical and acoustic properties based on two-dimensional finite-element method (2D-FEM) for Brillouin Gain spectrum (BGS) determination in optical fibers with COMSOL. This model enables us to predict precisely the BGS of any kind of silica fiber knowing well the geometry of doping composition. The results of numerical modeling have shown good agreement in ...

Drug therapy of the posterior part of an eye is very challenging. Yet, in USA alone, there are almost 2 million people affected by age related macular degeneration. When designing a strategy for controlled-release drug delivery, it is important to take into account of physiology, absorption, distribution, metabolism, and excretion properties of a drug. Therefore, the aims of this study are: 1) to ...

The axial injection torch (AIT) produces high-density plasmas by coupling microwave power to a flowing gas. The plasma is imposed by defining its electron density and temperature whose maximum are given by optical emission spectroscopy diagnostics. Our study of an AIT with COMSOL Multiphysics is for the following modules: - electromagnetic (3D), to calculate the distribution of the ...
