Multiphysics Simulations for the Design of a Superconducting Magnet for Proton Therapy

C. Calzolaio [1], H. Carolin [1], S. Stephane [1],
[1] Paul Scherrer Institut, Villigen, Switzerland

The use of proton therapy for cancer treatment shows a growing trend, since the radiation dose delivered to the target volume is maximized and the dose to the surrounding healthy tissues is minimized. To direct the proton beam from all directions to the tumor in the patient, the last ... En savoir plus

Numerical Model Simulation of Impedance Based Control for RF Ablation Using Isolator Synergy Clamp

M. Etheridge [1], R. Lopusnik [1], A. Cates [1],
[1] AtriCure, Inc., Minnetonka, MN, USA

Thermal ablation is rapidly becoming a standard of care for the treatment of atrial fibrillation (AF), a cardiac disorder characterized by irregular heart rhythm and estimated to impact more than 33 million people worldwide (Chugh et al. Circulation (2013)). AtriCure is a company that ... En savoir plus

Evaluation of the Induced Excitation of the Peripheral Vestibular System Using Micro Scale Inductors

S. Mukesh [1], P. Bhatti [1],
[1] School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA

According to the National Health and Nutrition Examination Survey data, 35 % of US adults aged 40 years and older have evidence of balance dysfunction based on the modified Romberg test. In this vestibular dysfunction, patients are not able to see stabilized images on their retina during ... En savoir plus

Multiphysics Modeling of the Graphite Electrode Joint in Electric Arc Furnaces for Steel Recycling

N. May [1], M. Waldner [2],
[1] GrafTech International Holdings, Inc., Independence, OH, USA
[2] Case Western Reserve University, Cleveland, OH, USA

Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... En savoir plus

Remote Monitoring of Structures in Composite Materials via Embedded Thermo-Chemical Sensors

B. Golchinfar [1], M. Rutner [1], D. Donskoy [1],
[1] Stevens Institute of Technology, Hoboken, NJ, USA

Composite systems are becoming more and more widespread across industries and the capability to finding and tracking internal defects before they have grown to major deterioration is of paramount importance in regard to safety, economy and maintenance. We are exploring a novel method of ... En savoir plus

Electromagnetic Characteristics of Superconducting Coils Exposed to Travelling Magnetic Fields

Tianyong Gong [1],
[1] Southwest Jiaotong University, Chengdu, China

Two-generation superconducting coils carrying large current in alternating magnetic fields is very common in electrical applications such as HTS linear motor. So it is meaningful to study the characteristics of coated superconductors in the presence of travelling magnetic field. In this ... En savoir plus

Evaluation of Electromagnetic Heating of a Composite Material Using COMSOL Multiphysics® Software

[1] Siemens technology and services private limited, Bangalore, Karnataka, India
[2] IIT Madras, Chennai, India.

Carbon fiber as filaments or as continuously reinforced composite finds application in the electronic packages, electric vehicles, and electrical machines, owing to its excellent electromagnetic (EMI) shielding and high conductivity. Carbon fiber being good conductor of electricity (in ... En savoir plus

Modeling Post Convection Cooling of High Power Waveguide

H. V. Dixit [1], A. R. Jadhav [2], Y. M. Jain [3], A. N. Cheeran [1], V. Gupta [2], P. K. Sharma [3],
[1] Veermata Jijabai Technological Institute, Mumbai, Maharashtra, India
[2] Vidyavardhini's College of Engineering and Technology, Vasai, Maharashtra, India
[3]Institute for Plasma Research, Gandhinagar, Gujarat, India

Waveguide Structures are often used for transmission of high CW power. The inherent conductor losses in the waveguide material lead to an increase in its temperature. If appropriate thermal management is not undertaken, this high temperature may lower the breakdown threshold of the ... En savoir plus

Modeling Radiofrequency Ablation of a Spherical Breast Tumor

R. Repaka [1], S. Singh [1], , ,
[1]Indian Institute of Technology Ropar, Rupnagar, Punjab, India

A three-dimensional heterogeneous model of breast has been modeled with a spherical tumor of 1.5 cm. PID controller has been used to perform temperature-controlled RFA of breast tumor. The coupled effect of blood perfusion and variable conductivity during RFA has been investigated. The ... En savoir plus

Simulation of the Thermal Expansion of an Inductively Heated Gear Wheel for Shrink Fitting Purposes

C. Hollenbeck [1], Z. Jildeh [1], T. Rydlewski [1], P. Kirchner [1],
[1] Imagine Engineering GmbH, Bergheim, Germany

Due to the advantages of induction heating as a method for precise and efficient local heating, it is perfectly suited for thermal shrink fitting of a gear wheel on a shaft. In this work, a simulation model was established to study the induction heating of a gear wheel, its thermal ... En savoir plus
