Heat Transfer and Phase Transformation on Matrix Assisted Pulsed Laser Evaporation (MAPLE) of Biocompatible Thin Layers

E. Lacatus[1], G.C. Alecu[1], M.A. Sopronyi[2], A. Tudor[1]
[1]POLITEHNICA University of Bucharest, Bucharest, Romania
[2]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique is used for the deposition of high quality biocompatible polymer thin films. During the deposition process the temperature of the laser target should be kept below 193K to assure the proper quality of both evaporation and ... Mehr lesen

Fluid-structure Interaction Modeling of Air Bearing

[1]ASML - MDev – Mechanical analysis, Veldhoven, The Netherlands
[2]ASML - MDev – System Dynamics, Veldhoven, The Netherlands

Air bearings are special type of bearings which provide nearly zero friction between two surfaces. This is achieved by a compressed layer of gas between the surfaces. This study presents a modeling technique for an Air bearing component. COMSOL Multiphysics® is used to efficiently ... Mehr lesen

An MHD Study of the Behavior of an Electrolyte Solution Using 3D Numerical Simulation

L. P. Aoki[1], H. E. Schulz[1], M. G. Maunsell[1]
[1]University of São Paulo, São Carlos, SP, Brazil

This article considers a closed water circuit with square cross section filled with an electrolyte fluid. The conductor fluid was moved using an electromagnetic pump, in which a permanent magnet generates a magnetic field and electrodes generate the electric field in the flow. Thus, the ... Mehr lesen

Fluid-Structure Interaction Modeling of High-Aspect Ratio Nuclear Fuel Plates Using COMSOL Multiphysics®

F. Curtis[1], K. Ekici[1], J. D. Freels[2]
[1]The University of Tennessee, Knoxville, TN, USA
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

The High Flux Isotope Reactor at the Oak Ridge National Lab is in the research stage of converting its fuel from high-enriched uranium to low-enriched uranium. One of the areas being explored is the fluid-structure interaction phenomenon due to the interaction of thin fuel plates (50 ... Mehr lesen

RF Hot-Zone Location within Rectangular Confined Spaces

R. Rodriguez[1]
[1]University of the West Indies, St. Augustine, Trinidad and Tobago

RF propagation modelling in (30 – 1000 MHz) SAR region for predicting the location and intensities of constructive interference patterns within rectangular confined spaces using waveguide theory and ray tracing techniques. Mehr lesen

Use of Simulation in the Development of Next-generation Measurement Standards for Radiation Dosimetry

R. E. Tosh[1], H. Chen-Mayer[1]
[1]NIST, Gaithersburg, MD, USA

Calibration of field instruments used in radiation treatment clinics is currently traceable to NIST primary standards via protocols involving static, flat-field radiation beams. By contrast, radiation beams prescribed for treating cancer incorporate temporal and spatial modulation ... Mehr lesen

Modeling of Transport Phenomena in Gas Tungsten Arc Welding of Ni to 304 Stainless Steel

A. Bahrami[1], D. K. Aidun[1]
[1]MAE Department, Clarkson University, Potsdam, NY, USA

COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ...

Simulation of Radiation Dose from Diagnostic X-ray Beams

H. Chen-Mayer[1], R. E. Tosh[1]
[1]NIST, Gaithersburg, MD, USA

Direct realization of absorbed dose to water in diagnostic radiation via calorimetric methods poses many challenges since the thermal signal of interest may be less than a few microKelvin. In actual biological systems or structures, like the lung, there is the additional complication of ... Mehr lesen

Phase-sensitive Microcalorimetry for Study of Low-level Radioactive Sources

H. Chen-Mayer[1], R. E. Tosh[1]
[1]NIST, Gaithersburg, MD, USA

Microcalorimetry for standardizing activities of radionuclide samples entails measurements of input power heat flow from the sample cell, with the radioactive sample compared to the reference cell under balanced conditions. The measurement is susceptible to noise due to drift and 1/f ... Mehr lesen

Finite Element Analysis of Photoacoustic Response from Gold Nanoparticle

Y. Davletshin[1], J. C. Kumaradas[1]
[1]Ryerson University, Toronto, ON, Canada

Photoacoustic (PA) imaging has matured into a clinical modality for tissue imaging and functional cancer cell research. It uses a pulsed laser to irradiate a region and generate a thermally-induced acoustic pressure wave that can be collected by an ultrasound transducer. The optical ... Mehr lesen
