Wind Flow Modeling of Area Surrounding the Case Western Reserve University Wind Turbine

M. Fernandes[1], D. Matthiesen[1]
[1]Case Western Reserve University, Cleveland, OH, USA

The CWRU Turbine is a research turbine located in a urban campus in Cleveland, Ohio. This location may create turbulence, resulting in a possible loss in energy generation. This research attempts to answers the question of whether the wind flow is affected by the buildings or not. The ... En savoir plus

Numerical Study and Simulation in COMSOL Multiphysics of the Dilution Process during Dust Sampling in Dry Machining

B. Wenga-Ntcheping[1], A. Djebara[1], R. Kamguem[1], J. Kouam[1], V. Songmene[1]
[1]University of Quebec-École de Technologie Supérieure, Montreal, Canada

Dilution’s issue during dry machining have raised the interest’s environmental researchers and engineers. In fact, the sampling of dust emitted during dry machining was a serious problem for air quality evaluation at the workplace. Furthermore, the best sampling of fine and ultrafine ... En savoir plus

The Use of CFD to Simulate Turbulent Flows in Laboratory and Full Scale Flocculation Processes

A.H. Ito[1], O.T. Kaminata [1], S.R. Lautenschlager[1]
[1]State University of Maringá, Maringá, Paraná, Brazil

The hydraulic flocculates are employed in water treatment plants (WTPs), but may present problems during the mixing stage reducing the efficiency of treatment. In this context modeling of a hydraulic flocculate using COMSOL and a 1:10 scale model of the Maringá-PR Brazil city WTP ... En savoir plus

Cryogenic Heat Sink for Helium Gas Cooled Superconducting Power Devices

L. Graber[1], N.G. Suttell[1], D. Shah[1], D.G. Crook[1], C.H. Kim[1], J. Ordonez[1], S. Pamidi[1]
[1]Center for Advanced Power Systems, Florida State University, Tallahassee, FL, USA

Heat sinks for cryogenic applications using helium gas as the coolant are not readily available. They require to be designed specifically for the intended application. A finite element model was developed to study the feasibility and optimize the design. The FEM computing package COMSOL ... En savoir plus

Geometric Optimization of Micromixers

M. Jain[1], A. Rao[1], K. Nandakumar[1]
[1]Cain Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA, USA

The performance of a homogeneous T-mixer can be enhanced significantly by the stimulation of secondary/ transverse flows in the microchannel. Various mixing mechanisms are reported for enhancing micromixing performance such as grooves at the channel bottom, heterogeneous charge patterns ... En savoir plus

A Computational Approach for Optimizing the First Flyer Using COMSOL Multiphysics

A.H. Aziz[1], H. Pourzand[1], A.K. Singh[1]
[1]Pennsylvania State University, University Park, PA, USA

COMSOL Multiphysics software was used to structurally optimize the Wright brothers’ flyer. The flyer was drawn in SolidWorks, imported and meshed in COMSOL. COMSOL Solid Mechanics module was used to analyze the flyer. Four of the sixteen struts were removed yet the structural ... En savoir plus

Computationally Assisted Design and Experimental Validation of a Novel ‘Flow-Focussed’ Microfluidics Chip for Generating Monodisperse Microbubbles

M. Conneely[1], V. Hegde[2], H. Rolfsnes[1], A. Mason[2], D. McLean[1], C. Main[1], F.J.D. Smith[2], W.H.I. McLean[2], P.A. Campbell[1]
[1]Carnegie Physics Laboratory, University of Dundee, Dundee, Scotland, United Kingdom
[2]Division of Molecular Medicine, University of Dundee, Dundee, Scotland, United Kingdom

Whilst initially developed as a diagnostic aid to improve echogenicity in ultrasound imaging, gas-filled lipid microbubbles are now emerging as a next generation \'theranostic\' tool in the medical arena. Here, their therapeutic potential has now been realized through their unique ... En savoir plus

Modeling of the Reduction Stage during the Continuous Refining of Copper in a Packed Bed Reactor

F. Mansilla[1], L. Voisin [2]
[1]Advanced Mining Technology Center, Chile University, Santiago, Chile
[2]Department of Mining Engineering, Advanced Mining Technology Center, Chile University, Santiago, Chile

Throughout history, the copper pyrometallurgical processes have been carried out mostly in discontinuous or batch systems. In recent decades new continuous technologies have been developed but focused only on Smelting and Converting stages leaving aside the Refining one. In 2002 a novel ... En savoir plus

Experimental Validation of Model of Electro-Chemical-Mechanical Planarization (ECMP) of Copper

J. Ebert[1], S. Ghosal[1], A. Emami-Naeini[1]
[1]SC Solutions, Sunnyvale, CA, USA

This paper describes the development of a COMSOL model of Electro-Chemical-Mechanical Planarization (ECMP) that was validated with experimental data. ECMP is used for processing of semiconductor wafers. We developed a 2D model of flow of phosphoric acid solution (the electrolyte) between ... En savoir plus

Modeling Void Drainage with Thin Film Dynamics

J.J. Gangloff Jr.[1], W.R. Hwang[2], S.G. Advani[1]
[1]Center for Composite Materials, Department of Mechanical Engineering, University of Delaware, Newark, DE, USA
[2]School of Mechanical Engineering, Gyeongsang National University, Jinju, Gyeongsangnam-do, Korea

Voids in composite materials can lead to degraded structural performance. The following is a study of voids or bubbles in uncured viscous polymer resin during composites processing. The goal is to determine if voids can successfully migrate towards vacuum pathways, coalesce with the ... En savoir plus
