Software Management Plan for Grade D Acquired Software COMSOL

This document has been produced by Washington River Protection Solutions, LLC on behalf of the Department of Energy (DOE) for the use of COMSOL when simulating applications related to DOE's waste management. COMSOL has been classified as a grade D acquired software program and this ... Read More

Numerical Study on Shear Horizontal Electromagnetic Acoustic Transducers for Generation of Ultrasonic Guided Waves for Absorber Tubes used in Concentrated Solar Plants

L. Cheng[1], A. Mohimi[1], M. Kogia[1], V. Kappatos[1], C. Selcuk[1], T.-H. Gan[1]
[1]Brunel Innovation Centre, Brunel University, Uxbridge, UK

Absorber tubes are one of the most critical components of parabolic trough Concentrated Solar Plants, which is very likely get damaged such as crack and mass loss. Therefore, the monitoring of their structural health via Non-Destructive Testing (NDT) techniques is regarded as essential ... Read More

Numerical Quasi Stationary and Transient Analysis of Annular Linear Electromagnetic Induction Pump

L. Goldsteins[1], L. Buligins[2], Y. Fautrelle[3], C. Biscarrat[1], S. Vitry[1]
[1]CEA Cadarache, Saint Paul lez Durance, France
[2]University of Latvia, Riga, Latvia
[3]Grenoble Institute of Technology, Grenoble, France

In this paper an axisymmetric model of annular linear electromagnetic induction pumps using numerical methods and four approaches (two transient and two quasi-stationary) with different complexity is studied. Comparison of integral characteristics is performed between numerical ... Read More

3D Modeling of Urban Areas for Built Environment Applications Using COMSOL

J. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

This paper presents the modeling and simulation results of wind velocities in urban areas. The main idea was to build random generated urban areas for studying the influence of different urban geometries, from relative open to more dense, on wind profiles. The Spalert-Allmaras turbulent ... Read More

Numerical Modeling and Performance Optimization Study of a Dehumidification Process in Nuclear Waste Storage

P. Geraldini[1]
[1]Sogin Spa, Rome, Italy

One of the main parameters to consider during the nuclear waste storage design phase is the drum corrosion risk. The humid-air corrosion models available in literature predict that, for carbon steel, the phenomena start to become appreciable for relative humidity (RH) values close to ... Read More

Low Reynolds Number Flow Around a Flying Saucer Micro Air Vehicle

S. Cortés[1], D. Güemes[1], R. Ávila[1]
[1]Universidad Nacional Autónoma de México, Mexico City, Mexico

The study of low Reynolds number flow around air vehicles of the order of centimeters. According to DARPA, a NAV is defined as a vehicle with 7.5 cm of length and weight of 20 grams. We calculated the flow around a small length scale 3D rigid body with complex geometry. Firstly we ... Read More

Simulation of Heat Transfer on Periodic Microstructured Surfaces for Evaporation Cooling

M. Hackert-Oschätzchen[1], R. Paul[1], M. Penzel[1], M. Zinecker[1], A. Schubert[1]
[1]Professorship Micromanufacturing Technology, Technische Universität Chemnitz, Chemnitz, Germany

Evaporative cooling is a promising cooling method for dissipating high heat fluxes in high power density applications. One possibility to enhance heat flux is a generation of microstructures into the cooler surface. This enlarges the cooler surface and systematically affects the fluid ... Read More

Determination of the Mechanical Properties in the Avian Middle Ear by Inverse Analysis

P. Muyshondt[1], J. Soons[1], D. de Greef[1], J. Peacock[1], J. Dirckx[1]
[1]University of Antwerp, Antwerp, Belgium

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... Read More

Sub-Millimetric Vacuum Electron Gun Design and Characterization

A. Leggieri[1], G. Ulisse[1], F. Di Paolo[1], F. Di Paolo[1], A. Di Carlo[1]
[1]University of Rome "Tor Vergata" - Department of Electronic Engineering, Rome, Italy

This paper presents the design of an electron gun that could be employed for vacuum tubes operating in the THz range. In this context, vacuum tubes one of the main difficulties in the realization of THz vacuum tube is the design and the realization of the electron gun. Since the ... Read More

Temperature Gradients Controlled Broadband Acoustic Omnidirectional Absorber

F. Qian[1], L. Quan[1], X. Liu[1]
[1]Institute of Acoustics and School of Physics, Nanjing University, Nanjing, China

Previous research into acoustic omnidirectional absorber (AOA) has shown the feasibility of forming acoustic black hole to guide the incident wave into the central absorptive cavity. However, major restrictions to practical applications exist due to complexity of designing metamaterials ... Read More
