Numerical Simulation of Oil Recovery by Polymer Injection using COMSOL

J. Wegner[1], L. Ganzer[1]
[1]Clausthal University of Technology, Clausthal, Germany

In this paper we used COMSOL Multiphysics to model basic physico-chemical effects relevant in polymer enhanced oil recovery (EOR) such as non-Newtonian rheology of the displacing phase, permeability reduction, adsorption and salinity effects. COMSOL\'s PDE interface as well as Species ... Read More

Design Of Acoustic Metamaterials Based On The Concept Of Dual Transmission Line

A-S.Moreau[1], H.Lissek[1], and F. Bongard[2]
[1]Ecole Polytechnique Fédérale de Lausanne, Switzerland
[2]JAST SA, Antenna Systems, Lausanne, Switzerland

In this context, a one-dimensional acoustic transmission line, exhibiting metamaterial properties, is presented. It is composed of an acoustic waveguide, periodically loaded with membranes having the function of series capacitances, as well as transversally connected open channels ... Read More

COMSOL Multiphysics® Models Combined with Experiments to Teach PID Controller Tuning

W. Clark[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

A laboratory exercise to learn PID controller tuning can be time consuming and taxing on the equipment. A purely equation-based, virtual controller tuning exercise might not seem relevant to real world processes. We have combined a physical process with a COMSOL Multiphysics model to ... Read More

The Full-System Approach for Elastohydrodynamic Lubrication

N. Fillot[1], T. Doki-Thonon[1], and W. Habchi[2]
[1]CNRS, INSA, Université de Lyon, Lyon, France
[2]Department of Industrial and Mechanical Engineering, Lebanese American University, Byblos, Lebanon

A ball is in contact with a plane, and a lubricant separates the two surfaces to decrease friction during their relative motion. To avoid wear, the lubricant film thickness should be higher than the surface roughness. The goal of this paper is to show how it is possible to solve ... Read More

Modelization of Photoacoustic Trace Gases Sensors

B. Parvitte[1], C. Risser[1], R. Vallon[1], V. Zéninari[1]
[1]GSMA - Université de Reims, Reims, France

This paper aims to demonstrate the simulation of photoacoustic signals using FEM software. The Acoustics Module of the software COMSOL Multiphysics is used to calculate the response of a differential Helmholtz resonator cell. In a second part a preliminary result obtained with the ... Read More

Multiphysics FEM Simulations Approach for Development of a MEMS Heat Generator

G. S. Masi[1], S. V. De Guido[1], G. Montagna[2], C. Martucci[2], P. M. Congedo[1], L. Vasanelli [1], M. G. Manera[2], R. Rella[2]
[1]Department of Innovation Engineering, University of Salento, Lecce, Italy
[2]CNR-IMM, Lecce, Italy

Introduction: Accurate fluid temperature control in microfluidic channels is a requirement for many lab-on-chip and micro-reactors.Thin films resistive metal heaters have proven to be the best choice for localizing heating applications with integrated microfluidic systems. A thin ... Read More

Towards Rotordynamic Analysis with COMSOL Multiphysics

M. Karlsson[1]
[1]ÅF, Stockholm, Sweden

In this paper a pre-study on using COMSOL Multiphysics for rotordynamic analysis is presented. It is concluded that it is possible to use COMSOL Multiphysics to perform rotordynamical analysis. However, there are no standard environment for rotordynamics, hence the user has to extend the ... Read More

The Campi Flegrei Deep Drilling Project ‘CFDDP’: Understanding the Magma-water Interplay at Large Calderas

G. De Natale[1], G. Perillo[2], C. Troise[1], and P. Gasparini[3]
[1]INGV-Osservatorio Vesuviano, Naples, Italy
[2]Università degli Studi di Napoli Parthenope, Naples, Italy
[3]AMRA scarl, Naples, Italy

Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. It has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, making it a natural candidate ... Read More

Investigation of Transport Phenomena in Nanochannels and its Applications in Energy Conversion using COMSOL Multiphysics

Chih-Chang Chang[1]
[1]Green Energy and Environment Research Laboratories, Industrial Technology Research Institute, Chutung, Hsinchu, Taiwan

Well‐designed and controlled nanochannels are ideal physical modeling systems to study fluidics in a precise manner. Electrokinetics refers to transport phenomena related to the non‐electroneutral EDL, which is created to neutralize the surface charges produced on surface. Surface ... Read More

Finite Element Modeling for the Mechanical Behavior of Silicon Diaphragms Using COMSOL Multiphysics^®

J. Ren[1], M. Ward[1], Peter Kinnell[2], and Russell Cradock[2]

[1]School of Mechanical Engineering, University of Birmingham, Birmingham, United Kingdom
[2]GE Druck Limited, Fir Tree Lane, Leicester, United Kingdom

The silicon diaphragm is one of the most common structures in Micro-Electromechanical Systems (MEMS). However, it is susceptible to creep deformation at elevated temperatures. This paper presents a transient finite element model which simulates the mechanical behavior of the ... Read More
