Ercan Dede, Toyota Research Institute of North America

Multiphysics Modeling Solutions for Advanced Vehicle Research & Development

Ercan Dede currently works as a Principal Scientist for the Toyota Research Institute of North America, where his research involves the multiphysics simulation and optimization of electromechanical systems for advanced vehicle applications. Dr. Dede received his Ph.D. and B.S., respectively, in 2007 and 1998 in Mechanical Engineering from the University of Michigan. From 1998 to 2003 he concurrently worked for Lockheed Martin Space Systems Company on spacecraft solar array and mechanisms design while earning an M.S. in Mechanical Engineering in design at Stanford University.

Abstract

A sustained interest in hybrid vehicles exists due to rising fuel costs and consumer demand for efficient transportation. As a result of these requirements, hybrid vehicles are subject to challenging cost, packaging, and performance constraints. These constraints are logically linked to advanced electromechanical systems and materials inside of these vehicles, and the design of these components typically requires the consideration of multiple physical processes including electromagnetics, fluid flow, heat transfer, and/or structural mechanics.

Product development strategies that integrate multiphysics modeling enable prototype optimization and performance prediction prior to fabrication. These simulations also support eventual prototype validation. Example modeling solutions will be discussed for different applications including electronics cooling and electromagnetic actuators. Additionally, the role and growth of multiphysics modeling within the Toyota Research Institute of North America will be briefly reviewed. Hide Abstract



Alan Leewood, MED Institute

Use of COMSOL Multiphysics® to Simulate RF Heating of Passive Conductive Implants in MRI Scanners

Dr. Leewood joined MED Institute (a Cook Medical Company) in January 2004. He came to MED from AC Engineering, Inc.(ACE) which he founded in 1986. ACE provided consulting services in the field of Computer Aided Engineering with specialty in solving a wide range of industrial problems requiring expert use of nonlinear FEA, in particular the ABAQUS® program. Dr. Leewood was brought into MED to kick-start its own CAE capabilities as well as create an R-Phase new product development team. Current responsibility as Director of Advanced Engineering requires that Dr. Leewood keep the most current technologies, including advanced simulation software, available for use in the new product design process. Dr. Leewood received his PhD in AeroSpace Engineering from Purdue University in 1985. Read Abstract

Abstract

An MRI scan makes use of a radio frequency (RF) coil to produce a time varying circularly polarized magnetic field for the purpose of imaging. In the case of in-vivo conductive medical devices, such as stents and vena cava filters, it is possible that at near resonant lengths localized electrical fields can be generated to create heating in the tissue adjacent to the devices. Safety of these devices demands that these localized temperatures be known such that it can be assured cell death is avoided. This talk will discuss the application of COMSOL Multiphysics® to a coupled electromagnetic-heat transfer analysis and experimental validation of the same utilizing ASTM testing methods and a commercial medical device.

William Vetterling, ZINK Imaging

COMSOL Multiphysics and The Library of Babel

William T. Vetterling, Ph.D., is a Research Fellow of ZINK Imaging, Inc. and manager of its Image Science Laboratory in Bedford, Massachusetts. He received his Ph.D. in condensed-matter physics from Harvard University, and joined the Harvard faculty in 1976. In 1984 he began working with Polaroid Corporation, where he remained for over 20 years performing research and modeling studies of imaging systems, including CCD, CID and CMOS imagers, photodiodes, color liquid-crystal displays, solid state lasers and several novel printing technologies. Since 2005, he has been collaborating in the development of a new color thermal-imaging process known as ZINK. In addition to his work in experimental physics and computer modeling, Dr. Vetterling is co-author of the Numerical Recipes series of books and software. He has published over 60 scientific articles and books, and has 30 U.S. patents. Read Abstract

Abstract

"The Library of Babel" is a fictional short-story by Argentinian writer Jorge Luis Borges (1899-1986). It describes a library with extraordinary features, said to have existed in the ancient city of Babel. We will spend a few minutes talking about the surprising and baffling contents of this library, and then about its subtle connection with modern-day COMSOL Multiphysics. Come and find out what this connection is! Hide Abstract
