Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

Plasmon Enhanced Fluorescence Characteristics Government by Selecting the Right Objective Function

M. Csete [1], A. Szenes [1], D. Vass [1], B. Bánhelyi [2], T. Csendes [2], G. Szabó [1]
[1] Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary
[2] Department of Computational Optimization, University of Szeged, Szeged, Hungary

Core-shell type plasmonic nanoresonators have been optimized to maximize the fluorescence rate of coupled dipolar emitters, namely SiV color centers in diamond. The RF module of the COMSOL Multiphysics® software was applied to extract the optical response and to analyze the near-field ... 詳細を見る

Multiphysics Simulation of 2nd Generation 238Pu Production Designs Using the COMSOL Multiphysics® software

C. J. Hurt [1], J. D. Freels [1], A. Elzawawy [2],
[1] Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2] Vaughn College of Aeronautics and Technology, East Elmhurst, NY, USA

In order to qualify experiments for in-vessel irradiation at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, safety assessments need to be completed and documented to ensure adequate target cooling and structural integrity. Previously, finite element analysis ... 詳細を見る

Multidisciplinary Simulation Based Learning Enhancement Module

A. K. Datta [1], M. Ukidwe [1], A. Warning [1], K. Bhunia [1],
[1] Cornell University, Ithaca, NY, USA

Simulation based learning modules can be effectively introduced to a large audience with customization. The simulation modules can essentially engage learners from diverse background and efficiently introduce the quantitative approaches to non-engineers. Moreover, those can greatly help ... 詳細を見る

Generation of SFQ-Pulses in SNS-Junctions: Learning Physics using the COMSOL Multiphysics® software

A. M. Gulian [1], G. Melkonyan [2],
[1] Advanced Physics Laboratory, Chapman University, Burtonsville, MD, USA
[2] GMLabs, Quebec, QC, Canada

Single Flux Quantum, or SFQ, dynamics is at the heart of superconducting electronics. So are the Josephson junctions, or in a wider context, weakly-coupled superconducting junctions, in particular, superconductor-normal metal -superconductor, or SNS, junctions. Despite the COMSOL ... 詳細を見る

Effect of Duty Cycle Variation on Acoustic Pressure Field Simulation in an Ultrasound Bioreactor

A. Rahimi [1], J. Crapps [1], N. Case [1]
[1] Biomedical Engineering, Saint Louis University, Saint Louis, MO, USA

Daily application of a low intensity pulsed ultrasound (LIPUS) regimen has been shown to have positive effects on bone fracture healing. Although LIPUS treatment can induce cellular responses supporting bone repair, the underlying mechanisms are not well understood. Further in vitro ... 詳細を見る
