[1]Veryst Engineering LLC, Needham, MA, USA
[2]Nordson EFD, East Providence, RI, USA

Laminar flow static mixers are accurate, inexpensive fluid mixing devices that can handle a wide range of fluids and mixing proportions. They have a wide range of industrial applications, especially in the consumer product, pharmaceutical, biomedical, and petrochemical industries. A good ... Read More

Design and Prototyping of a Passive Cold Chain Vaccine Storage Device for Long Hold Times

D. Gasperino [1], O. Yildirim[1]
[1]Intellectual Ventures, Bellevue, WA, USA

In 2010 an estimated 109 million infants were immunized against DTP, which serves as a good proxy for vaccinations in general. At the same time, however, approximately 19.3 million infants worldwide were not reached by routine DTP immunization services. Immunization rates tend to be ... Read More

Simulation of Differential Ion Mobility (DMS) Principle Coupled with Mass Spectrometry in Atmospheric Pressure

F. Sinatra[1], T. Wu[2], A. Avila[2], E. Nazarov[1], T. Evans-Nguyen[1], J. Wang[2]
[1]Draper Laboratory, Tampa, FL, USA
[2]University of South Florida, Tampa, FL, USA

Mass spectrometry is an analytical technique widely used in the scientific community to determine chemical composition of sample compounds. Typically, mass spectrometers perform their analysis under vacuum conditions, though atmospheric pressure mass spectrometers are becoming more ... Read More

COMSOL-based Simulations of Criticality Excursion Transients in Fissile Solution

C. Hurt[1], P. Angelo[2], R. Pevey[1]
[1]Department of Nuclear Engineering, University of Tennessee, Knoxville, TN, USA

Passive Microsensor Based on LC Resonators for Substance Identification

D.A. Sanz Becerra[1], E.A. Unigarro Calpa[1], J. Osma[1], F. Segura[1]
[1]Universidad de los Andes, Bogotá, Colombia

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital ... Read More

Modeling Fluid-Induced Porous Scaffold Deformation

J. Podichetty Thribhuvan[1], S.V. Madihally[1]
[1]Oklahoma State University, Stillwater, OK, USA

Utilization of bioreactors to regenerate tissues outside the body has been intensely investigated in functional tissue engineering. Various studies have been performed using computational fluid dynamics (CFD) to understand fluid flow within bioreactors while assuming porous scaffold as a ... Read More

Multiphysics Modelling of Standing Column Well and Implementation of Heat Pumps Off-Loading Sequence

A. Nguyen[1], P. Pasquier[1], D. Marcotte[1]
[1] Department of Civil, Geological and Mining Engineering, École Polytechnique de Montréal, Montréal, QC, Canada

A fully coupled multiphysics model involving heat transfer and groundwater flow within a SCW and its surrounding ground was implemented in COMSOL Multiphysics 4.2a with MATLAB to simulate a 24-hour heating operation. The heat pumps were modeled using interpolation functions thereby ... Read More

Modeling and Experimental Verification of the Power Transfer and Thermal Characteristics of Piezoelectric Transformers Subjected to Combined Mechanical and Electrical Loading

S. Tuncdemir[1], W.M. Bradley[2]
[1]Solid State Ceramics, Williamsport, PA, USA
[2]QorTek, Williamsport, PA, USA

A piezoelectric transformer allows purely mechanical transfer and scaling of electrical energy via simultaneous utilization of both the direct and converse piezoelectric effects. This mechanical energy transfer enables a wide range of functional differences from typical magnetic-based ... Read More
