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 ... Read More

[3]Istituto Nazionale Fisica Nucleare - Sezione di Catania, Catania, Italy; Dipartimento di Fisica ed Astronomia, Università 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 [1]. A new GEM tracker is under development for the upgrade of the SBS ... Read More

Elastoplastic Deformation in a Wedge-Shaped Plate Caused by a Subducting Seamount

M. Ding[1], J. Lin[2]
[1]MIT/WHOI Joint Program in Oceanography, Cambridge, MA, USA
[2]Woods Hole Oceanographic Institution, Woods Hole, MA, USA

We used COMSOL Multiphysics 4.3 to simulate the 2D elastoplastic deformation and plastic strain in a wedge-shaped plate above a subducting interface. The modeling results reveal that a pair of conjugate normal faults would first appear in the thinner part of the plate. Subsequently, a ... Read More

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 ... Read More

Upscaling of Heterogeneous Rock Properties via a Multiscale Image to Simulation Approach

S. Zhang[1], M. Pal[2], P. Barthelemy[1], M. Lei[1]
[1]Visualization Sciences Group, Burlington, MA, USA
[2]Shell International Exploration and Production, Rijswijk, The Netherlands

The mass and recoverability of oil and gas in unconventional reservoirs strongly depend on the understanding the petrophysical properties of the rocks at a large range of scales. Three-dimensional imaging is capable of unveiling the detailed microstructures within the rocks down to the ... 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

A Study into the Acoustic and Vibrational Effects of Carbon Fiber Reinforced Plastic as a Sole Manufacturing Material for Acoustic Guitars

J. O'Donnell[1], G. McRobbie[1]
[1]University of the West of Scotland, Paisley, Scotland, United Kingdom

This study will research a modern design of acoustic guitar by analysis of the vibrational modes. The guitar that will undergo testing has been provided by Emerald Guitars and is solely constructed using Carbon Fiber Reinforced Plastic (CFRP). With the use of COMSOL Multiphysics© the ... Read More

Numerical Simulation of pH-sensitive Hydrogel Response in Different Conditions

M.K. Ghantasala[1], B.O. Asimba[1], A. Khaminwa[1], K.J. Suthar[2], D.C. Mancini[3]
[1]Department of Mechanical and Aeronautical Engineering, Western Michigan University, Kalamazoo, MI, USA
[2]Advanced Photon Source, Argonne National Laboratory, Argonne, IL, USA
[3]Physical Sciences and Engineering, Argonne National Laboratory, Argonne, IL, USA

The understanding of pH-sensitive hydrogel swelling response in different buffer environmental condition is essential for its use in different practical applications. This necessitates its simulation in steady state and transient conditions. This paper mainly deals with the details of ... Read More

Contactless Power and Data Transfer for Multiple Nonlinear Loads

H.P. Schmidt [1], U. Vogl[1]
[1]UAS HAW Amberg-Weiden, Amberg, Germany

For the design of an inductive power and data transfer electromagnetic calculation are carried out. A transfer system is considered for loads that are distributed across some distances. For example, such loads are adjustable speed drives that are found in factory automation and intra ... Read More

Computational Analysis of Evaporation in Tailored Microchannel Evaporators

S. Arslan[1], J. Brown[1]
[1]Lawrence Technological University, Southfield, MI, USA

The rapid increase in power densities of integrated circuits has induced a significant interest in new reliable and high heat flux cooling technologies. The implication of such growth is the increased need for more efficient and more compact cooling mechanisms. Promising research has ... Read More
