Optimization of Mechanical Properties of Superconducting Cavities for Project X LINAC

I. Gonin[1], M. Awida[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermilab, Batavia, IL, USA

Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, ... Read More

Investigation of Thermal Contact Gas Gap Conductance Using COMSOL Multiphysics®

J. D. Freels[1], P. K. Jain[1], C. J. Hurt[2]

[2]The University of Tennessee, Knoxville, TN, USA

Our safety analysis group in the Research Reactors Division of Oak Ridge National Laboratory supports a project to investigate the production of Pu-238 isotope for missions of deep space travel in the High Flux Research Reactor. COMSOL Multiphysics® has been used to support this activity ... Read More

Deformable Image Registration for Pleural Photodynamic Therapy

B. Liu[1], T. C. Zhu[1]
[1]Department of Radiation Oncology, School of Medicine, University of Pennsylvania, Philadelphia, PA, USA

Deformable image registration is a form of medical image processing that can provide insights into the development of phenomenon and variation in normal anatomical structure over time. Prior to post-operative pleural photodynamic therapy (PDT), a series of CT scans of lungs will be ... Read More

Simulation and Analysis of Two Fans Air Speed Match Design in Off-Road Mine Tract Generator Using COMSOL

Y. Shen[1], D. Wu[1]
[1]Beijing University of Science & Technology, Beijing, China

This paper describes a model of self-ventilated generator cooling on a 170 tons off-road mine dump truck. Considering the space restrictions of mine dump truck, the cooling systems for the generator and the in-wheel motors of the rear axle share one air inlet duct. With the action of ... Read More

Modeling the Temperature-Dependent Dynamic Behavior of a Timber Bridge with Asphalt Pavement

B. Weber[1]
[1]Empa, Swiss Federal Laboratories for Materials Science and Technology, Dübendorf, Switzerland

The fundamental frequency and the corresponding damping value are the main design parameters for footbridges against excessive vibrations induced by pedestrians. Since pedestrians typically walk at a pace of 1.6–2.4 Hz, this frequency range as well as the range of the second harmonic, ... Read More

Elasto-Plastic FEM Models Explain the Emplacement of Shallow Magma Intrusions in Volcanic Complexes

A. Bistacchi[1]
[1]Università degli Studi di Milano Bicocca, Milano, Italy

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone ... Read More

Modeling of the Photo-Mechanical Response of Liquid-Crystal Elastomers

[1]DICAR, Politecnico di Bari, Bari, Italy

Introduction: Improving the capability of nondestructive evaluations requires the analysis of suitable models dealing with the physical and mechanical phenomena involved in the experiments. For example, ultrasonic tests may be a powerful, fast and effective method for nondestructive ... Read More

An Innovative Solution for Water Bottling Using PET

D. Scardigno[1], A. Castellano[1], P. Foti[1], A. Fraddosio[1], S. Marzano[1], M.D. Piccioni[1]
[1]DICAR, Politecnico di Bari, Bari, Italy

Introduction: We study an innovative technology for water bottling using PET, aimed at reducing the thickness of the plastic bottles. The goals are the reduction of the amount of plastic used for a single water bottle, the reduction of the packaging costs and more environmental ... Read More

The Non Linear Behavior of the Microplane Model in COMSOL

A. Frigerio[1]
[1]RSE, Milano, Italy

The safety of large civil structures is often evaluated by means of numerical models based on the Finite Element Method (FEM). In the last year, the elastic behavior of the Microplane Model was implemented in COMSOL because it is a promising approach able to overcome the limit typical of ... Read More
