Multifunctional Fluid Power Components using Engineered Lattice Structures

S. Newbauer, D. Cook, and D. Pettis
Milwaukee School of Engineering
Milwaukee, WI

Designing a component with multiple functions, e.g. load bearing and noise attenuation, can increase the effectiveness of each component and reduce the complexity of the overall system, thereby improving system efficiency as well. Current multifunctional components include metal foam. ... En savoir plus

Simulation of MEMS based Flexible Flow Sensor for Biomedical Application

D. Maji[1], C. P. Ravikumar[2], and S. Das[1]
[1]School of Medical Science and Technology, Indian Institute of Technology, Kharagpur, West Bengal, India
[2]Texas Instruments (India) Pvt. Ltd., Bangalore, India

Arterial disease, especially Coronary Artery Disease (CAD) is one of the leading causes of premature morbidity and mortality. During the flow, blood interacts with vessel wall mechanically and chemically which modulates the plaque formation in blood vessel leading to coronary artery ... En savoir plus

From Music to Non-Invasive Therapies via COMSOL Multiphysics® Models

E. Lacatus[1], G. C. Alecu[2], A. Tudor[2], M. A. Sopronyi[3]
[1]Polytechnic University of Bucharest, Bucharest, Romania
[2]Student-Polytechnic University of Bucharest, Bucharest, Romania
[3]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be ... En savoir plus

Integrated Model For Ocean Waves Propagating Over Marine Structures On A Porous Seabed

D-S. Jeng, X. Luo, and J. Zhang
Division of Civil Engineering, University of Dundee, Dundee, Scotland, UK

In this paper, an integrated model for ocean waves propagating over a submerged coastal structure, based on COMSOL Multiphysics, is presented. In the model, Navier-Stoke Equation is solved for the wave propagation and Biot’s poro-elastic model is solved for the porous seabed. The new ... En savoir plus

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 ... En savoir plus

Design and Analysis of a Wetting Lens for the Pinhole Cameras of a Two Phase Flow System

A. K. Reddy[1], T. Satyanarayana[1]
[1]Lakireddy Balireddy Autonomous College of Engineering, Mylavaram, A.P., India

The present work reports the fabrication process of micro lens for pinhole cameras, modeled using COMSOL Multiphysics®, by satisfying the wetting properties. Wetting is a change in contact angle between the liquid and solid surface area. The wetting properties are clearly understood in ... En savoir plus

Air Foil Bearings - A Modeling Approach

M. Bezemer-Krijnen[1], Y.H. Wijnant[1], A. de Boer[1]
[1]University of Twente, Enschede, The Netherlands

A first generation air foil bearing (AFB) is shown in Figure 1. AFBs induce, at higher rotating speeds, an air film between the journal and the top foil, which lowers the friction forces. The goal of this study is to develop a model of an AFB. The thickness of the air film depends on ... En savoir plus

Undergraduate Studies of Supersonic Flow from a Converging-Diverging Nozzle

K. Stein[1], N. Gessner[1], R. Peterson[1], A. Wiedmann[1]
[1]Department of Physics, Bethel University, St. Paul, MN, USA

Undergraduate studies are carried out to examine the supersonic flow from an axisymmetric converging-diverging nozzle. Flow in the nozzle is initiated by the rupture of a diaphragm that is positioned between the nozzle and a 1-gallon pressurized air tank. Simulations are carried out in ... En savoir plus

[1]DIMET Department, Faculty of Engineering, University “Mediterranea” of Reggio Calabria, Reggio Calabria, Italy

Constitutive properties of living cells are able to withstand physiological environment as well as mechanical stimuli occurring within and outside the body. We examined fluid flow and Neo-Hookean deformation related to the rolling effect. A mechanical model to describe the cellular ... En savoir plus

Multiphysics Simulation of a Self-heating Paraffin Membrane Microactuator

P. Lazarou[1], C. Rotinat[1]
[1]CEA LIST/DIASI/LRI, Paris, France

A grand variety of microactuator technologies and demonstrators has been introduced during the last years.
