Analysis of Electroosmotic Flow of Power-law Fluids in a Microchannel(1D)

K. SriNithin[1]
[1]IIT Kharagpur, Kharagpur, West Bengal, India

Electroosmotic flow of power-law fluids in a slit channel(1D) is analyzed. The governing equations are the Poisson–Boltzmann equation, the Cauchy momentum equation, Generalized Smoluchowski equation and the continuity equation are used to get shear stress, dynamic viscosity, and velocity ...

Use of COMSOL as a Tool in the Design of an Inclined Multiple Borehole Heat Exchanger

E. Johansson[1], J. Acuña[1], B. Palm[1]
[1]Royal Institute of Technology KTH, Stockholm, Sweden

A field of connected boreholes can be used both for cooling, heating and storage purposes. The boreholes transfer heat to or from the ground, which over time changes the temperature in the ground. It is important that the borehole field is properly sized and evaluated before the ... Read More

Post Harvest Cold Chain Optimization of Little Fruits

S. Marai[1], E. Ferrari[1], R. Civelli[1]
[1]DiSAA, University of Milan, Milan, Italy

This paper presents heat transfer 3-D models of a passive refrigeration system used to improve the shelf life and the quality of the perishable fruits. Passive refrigerator system uses the changing phase to keep temperature close to the melting temperature. A multi-step study was ... Read More

RFID-Enabled Temperature Sensor

I.M. Abdel-Motaleb[1], K. Allen [1]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value ... Read More

COMSOL Aided Design of an Extraction Pipe for the Electron Beam from a Plasma Focus Device

M. Valentinuzzi[1], E. Ceccolini[1], D. Mostacci[1], M. Sumini[1], F. Rocchi[2]
[1]Montecuccolino Nuclear Engineering Laboratory, University of Bologna, Bologna, Italy
[2]UTFISSM-PRONOC, ENEA, Bologna, Italy

The electron beam emitted backward by Plasma Focus devices is being investigated as a radiation source for IORT (Intra-Operative Radiation Therapy) applications. A Plasma Focus device is being developed to this aim. The electron beam is driven through an electron pipe made of stainless ... 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

Numerical Simulation of Flow Electrolysers: Effect of Various Geometric Parameters

P. Shukla[1], K. K. Singh[1], P. K. Gupta [1], S. K. Ghosh[1]
[1]Bhabha Atomic Research Centre, Trombay, Mumbai, India

Flow electrolysers find several applications in industry. They are used for production of metals and synthesis of chemicals, gases. Cleaning and preservation of old artifacts, electrolytic refining of metals, electrolytic winning of metals, alkaline water electrolysis, anodization, ... Read More

Development of a Multiphase, Multispecies Droplet Evaporation Model for Optimization of Desiccation Preservation Techniques

A. Sinkevich[1], S. Bhowmick [1], M. Raessi[1]
[1]University of Massachusetts Dartmouth, North Dartmouth, MA, USA

Biopreservation deals with the protection and storage of complex biologics such as proteins, lipids, and recently, mammalian cells. One preservation method, known as lyopreservation, involves placing a biologic inside a water droplet with some type of sugar excipient (sucrose, trehalose, ... Read More

Assessment of the SNR, G-Factor and Relative B1- Fields of Medical Radiofrequency Arrays new

G. Cook[1], F. Robb[2], M. Graves[1], D. Lomas[1]
[1]Department of Radiology, University of Cambridge, Addenbrooke's Hospital, Cambridge, UK
[2]GE Healthcare Coils, Aurora, OH, USA

MRI relies upon a static magnetic field which creates a net magnetic moment from proton spins and radio-frequency fields are generated to excite this magnetic moment into a perpendicular plane, where it can be detected through the use of an array of conductive loops. The optimal size ... Read More
