Tribological Behavior of Rubber on Glass in Prefilled Syringes

T. Langley [1], E. Gutierrez-Miravete [2], ,
[1] Rensselaer Polytechnic Institute, Troy, NY, USA
[2] Rensselaer at Hartford, Hartford, CT, USA

The primary enclosure of an injected formulation is almost exclusively comprised of a glass container (syringe) and an elastomer closure (i.e. plunger). A failed injection is anything that prevents the full dosage of the drug to be administered, whether that is a glass breakage or ... En savoir plus

Toward Nano-Scale Scanning Electrochemical Microscopy of Single Live Cells by Means of the COMSOL Multiphysics® software

Z. Ding [1], F. P. Filice [1], M. S. M. Li [1],
[1] Department of Chemistry, University of Western Ontario, London, ON, Canada

Scanning Electrochemical Microscopy (SECM) is a powerful noninvasive analytical technique employed in a variety of applications ranging from electrochemical characterization of material surfaces, to bioanalytical characterization of single live cells [1]. When applied to live cells, SECM ... En savoir plus

Thermal Bridging Calculation of Three Steel Stud Wall Assemblies with Benchmarking

M. Ghobadi [1],
[1] National Research Council Canada, Ottawa, ON, Canada

As a part of the Pan-Canadian framework for clean growth, Canada is intent on meeting its 2030 emission targets for which 17% of Canada’s total Green House Gas emissions come from buildings. Given this challenge, emphasis is being placed on developing building designs having greatly ... En savoir plus

Thermal and Hydraulic Modeling of Road Tunnel Joints

C. H. Klotoé [1], F. Duhaime [1], L. Guizani [1],
[1] Département de Génie de la Construction, École de technologie supérieure, Montréal, QC, Canada

This paper focuses on the use of the COMSOL Multiphysics® software to develop a 2D numerical model of expansion joints for road tunnels. The model was developed using the coefficient form PDEs interface. The model includes water and energy conservation equations. It takes into account ... En savoir plus

The Roberval Balance

D. W. Pepper [1], Z. J. Olsen [1], L. J. Olsen [1],
[1] University of Nevada - Las Vegas, Las Vegas, NV, USA

The Roberval Balance, invented in 1669 by French mathematician Gilles de Roberval, is a unique balance that has perplexed many upon first encountering the mechanism. This mechanism is a parallelogram that when its arms comprise a perfect parallelogram and the moveable weights or poises ... En savoir plus

Structure of a Classical Vortex Ring

J. M. Russell [1],
[1] Florida Institute of Technology, Melbourne, FL, USA

This talk is for users of the COMSOL Multiphysics® software who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. As part of a multi-year plan to develop proficiency in Equation ... En savoir plus

Simulator for the Development of Electromagnetic Heart Assist Devices

D. G. Hurd [1],
[1] Iowa State University, Ames, IA, USA

Every year, in the United States alone, more than 40,000 infants are born with congenital heart defects (CHD) and an additional 550,000 adults are diagnosed with heart failure. Every year, $110 billion is spent on treating heart attacks and $20-39 billion on heart failure in the US. The ... En savoir plus

Simulation of Magnetically Driven Peristaltic Pumps for Microfluidic Applications

L. Gritter [1], J. Crompton [1], K. Koppenhoefer [1], P. Nath [2]
[1] AltaSim Technologies, Columbus, OH, USA
[2] Applied Modern Physics, Los Alamos National Lab, Los Alamos, NM, USA

Microfluidic technologies can enable laboratory processes to be packaged in miniaturized and automated systems, allowing these processes to be performed with hand-held devices outside a laboratory environment. The practical usefulness of these “lab on a chip” systems has often been ... En savoir plus

Simulation of Laser Powder-bed Fusion Additive Manufacturing Process Using the COMSOL Multiphysics® software

K. Leung [1], A. Imanian [1],
[1] Technical Data Analysis, Inc., Falls Church, VA, USA

Additive manufacturing technology is becoming more popular for the fabrication of metal products as it offers rapid prototyping and large design freedom. However, part quality of components fabricated by current additive manufacturing technology is not comparable to that produced by ... En savoir plus

Simulation of an Oxygen Delignification Reactor in the Kraft Pulp Production Process

D. do Mato Lara [1], J. da Luz Maeiski [1], I. Neitzel [1]
[1] Faculdade de Telêmaco Borba, Telêmaco Borba, PR, Brazil

Oxygen delignification is a technology established worldwide and a common operation in pulp mills that use Kraft cooking. The reasons for using this technology are the reduction of organochlorine compounds in the effluents, and economy of chemicals in the bleaching stage. The objective ... En savoir plus
