Miscible Viscous Fingering of Pushed Versus Pulled Interface

S. Pramanik[1], M. Mishra[1]
[1]Indian Institute of Technology Ropar, Rupnagar, Punjab, India

Viscous fingering (VF) instability has been extensively studied over past several decades in the context of various industrial, environmental and chemical processes. We try to model miscible VF at pushed or pulled interfaces using COMSOL Multiphysics®. We study the effect of the positive ... Read More

Implicit LES for Two-Dimensional Circular Cylinder Flow by Using COMSOL Multiphysics® Software

M. Hashiguchi[1]
[1]Keisoku Engineering System Co.,Ltd., Tokyo, Japan

In this paper, implicit Large Eddy Simulation (LES) based on finite-element analysis is performed in order to investigate two-dimensional circular cylinder incompressible flow. Implicit LES attempts time-dependent flow computation with no explicit turbulence model. Here, two types of ... Read More

Thermo-Fluid Dynamic Modeling of Cu Based Metallic Foams for Heat Exchanger Applications

C.A. Biffi[1], A. Tuissi[1]
[1]National Research Council of Italy, Lecco, Italy

In this work the innovative concept is the use of a Cu based metallic foam, characterized by open cell structure, as active element for heat exchangers. The metallic foam, produced by liquid infiltration method, was introduced inside a Cu tube, as base element for the exchanger. In the ... Read More

Investigation of Mean-Flow Effects on Tubular Combustion Chamber Thermoacoustics Using a Burner Transfer Matrix Approach

A. Andreini[1], B. Facchini[1], A. Innocenti[1], D. Pampaloni[1]
[1]University of Florence, Florence, Italy

The paper presents a methodology to account for local mean-flow effects on thermo-acoustic instabilities to improve typical calculations performed under the zero-Mach number assumption. A 3D FEM model of a simplified combustor is solved with COMSOL Multiphysics® Pressure Acoustics ... Read More

Pore-Scale Simulation of Two-Phase Flow with Heat Transfer Through Dual-Permeability Porous Medium

H.A. Akhlaghi Amiri[1], A.A. Hamouda[1]
[1]University of Stavanger, Stavanger, Rogaland, Norway

This paper addresses one of the major challenges in water-flooded oil reservoirs, which is early water breakthrough due to the presence of high permeable layers in the media. COMSOL Multiphysics is used to model two phase (water and oil) flow in dual-permeability porous medium at micro ... Read More

Computational Modeling and Simulation of the Human Duodenum

B. Hari[1], S. Bakalis[1], P. Fryer[1]
[1]The University of Birmingham, School of Chemical Engineering, Edgbaston, Birmingham, United Kingdom

Worldwide attention in the computational modeling and simulation of the human intestine is increasing in order to help understand its complex behavior and improve health. Computational fluid dynamics is an essential tool to understand the mechanics and transport phenomena of the human ... Read More

Optimization of the Gas Flow in a GEM Tracker with COMSOL and TENDIGEM Development

F. Noto[1,2], V. Bellini[1,2], E. Cisbani[3,4], V. De Smet[1,5], F. Librizzi[6], F. Mammoliti[1,2], and C. Sutera[6]
[1]Dipart. di Fisica ed Astronomia, Università di Catania, Catania, Italy
[2]INFN – Sezione di Catania, Catania, Italy
[3]IINFN – Sezione di Roma - Sanità Group, Roma, Italy
[4]Italian National Institute of Health, Roma, Italy
[5]Haute Ecole Paul-Henri Spaak, ISIB, Bruxelles, Belgium
[6]NFN - Sezione di Catania, Catania, Italy

The Gas Electron Multiplier (GEM) technology has been proven to tolerate rate larger than 50 MHz/cm2 without noticeable aging and to provide the sub millimeter resolution on working chambers up to 45x45 cm2. A new GEM based tracker is under development for the Hall A upgrade at ... Read More

Multiphysics Applications for Sustainable Engineering and Industrial Processes

S. Savarese [1], L. Kremer [1], C. Sanjeu [1]
[1] Armelio, Les Ulis, France

While addressing the pressing need for better, more sustainable engineering and production improvements, Armélio has identified that easy-to-use, customized, multiphysics applications would fulfill customer requirements. Hence, we now design and deliver COMSOL Multiphysics® apps bringing ... Read More

3D Analysis of Cavitation in Control Valve by Pressure Variation

E. Luz[1], D. M. P. Cunha[2], V. H. C. Lemos[2]
[1]Universidade Federal do Pará - UFPA, Belém, PA, Brasil; Centro de Instrução Almirante Braz de Aguiar - CIABA, Belém, PA, Brasil
[2]Centro de Instrução Almirante Braz de Aguiar - CIABA, Belém, PA, Brasil

The phenomenon of cavitation can severely affect the working of valves used to control liquid flow. Cavitation occurs when the pressure is reduced and the water evaporates, forming bubbles. When bubbles pass into an area of higher pressure, they condense and collapse, releasing a large ... Read More

Multiphysics Modelling of Food Dehydration during RF Exposure

R. Renshaw[1]
[1]e2v Ltd., Essex, United Kingdom

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to waters high dielectric properties. An industrial dryer can be ... Read More
