COURSE DESCRIPTION


In response to the numerous evolving technologies and applications based on microscale flow and heat transfer, the present course has been developed to provide a broad, fundamental state-of-the-art review on this emerging topic. The course provides a comprehensive treatment of both single-phase flow and heat transfer and two-phase flow and heat transfer in microchannels. The course is directed to heat transfer specialists in the computer and electronics cooling industries, the automotive and the air-conditioning industries, the aerospace industry, and the micro- and compact heat exchanger industries. Furthermore, the course is addressed to Ph.D. students and post-doctoral researchers involved in this area of research. The course lecturers are internationally recognized experts in micro-scale (and macro-scale) research and applications. The course format is informal with significant interaction during and after the lectures.



COURSE LECTURERS

John R. Thome (Course Coordinator and Lead Lecturer) is Professor of Heat and Mass Transfer at the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland, where his research interests are two-phase flow and heat transfer in microscale and macroscale processes. He received his Ph.D. at Oxford University (1978) and ran his own international engineering consulting company from 1984-1998. He is the author of three books and received the ASME Heat Transfer Division's Best Paper Award in 1998 for his work on flow boiling heat transfer and the UK IOR J&E Hall Gold Medal (2008) for his work on refrigeration heat transfer. He has published extensively on boiling and two-phase flow in microchannels and micro-evaporators. He will lecture on two-phase flow and heat transfer.

Bruno Michel (Invited Lecturer) is Mgr. of Advanced Thermal Packaging at IBM Zürich Research Laboratory. He received his Ph.D. in bio¬chemistry/biophysics from the University of Zürich in 1988 and then joined the IBM, where he later started the Advanced Thermal Packaging group in 2003 on improved thermal interfaces and better miniaturized convective cooling. Main current research topics of the Zürich group are microtechnology/microfluidics for efficient chip and data center thermal management, hybrid liquid/air coolers, 3D packaging and thermophysics to understand heat transfer in nanomaterials and structures. He will speak on the state-of-the-art of computer cooling technologies.

Iztok Zun (Lecturer) is Professor and Head of the Laboratory for Fluid Dynamics and Thermodynamics, Faculty of Mechanical Engineering, University of Ljubljana, Slovenia. He received his Ph.D. at the University of Ljubljana (1976) and the JSMF Award in 2003. He has a very distinguished international reputation on transient characteristics and multi-scale modeling of two-phase flows for a wide range of two-phase processes and their industrial application. He is working on visualization and modeling of two-phase flows in headers of multi-microchannel elements, elongated bubble flows and bubble coalescence. He will lecture on the numerical simulation of single-phase microchannel cooling elements and the status of numerical techniques for two-phase flows in microchannels of simple and complex geometry.

Gian Piero Celata (Lecturer) is Director of the Institute of Thermal-Fluid Dynamics at the Italian national research center ENEA and is honorary chair of the European Two-Phase Flow Group among his many international appointments. He received his Ph.D. at the University of Rome (1980) and the JSMF Award in 2003. He is a world expert on measurement and prediction of critical heat fluxes and has in recent years done extensive research on single-phase flow and boiling heat transfer in microchannels, including work at zero gravity and on heat pipes. He is also very well known for the numerous international research conferences he has organized and chaired and he has edited numerous books. He is a Member of the European Academy of Sciences and Arts. He will focus his lectures on the state-of-the-art of single-phase heat transfer and fluid flow in simple and complex geometries and on condensation and boiling heat transfer in microchannels.

Anthony M. Jacobi (Lecturer) is Kritzer Distinguished Professor of the Department of Mechanical Science and Engineering at the University of Illinois Champaign-Urbana and is Co-director of the Air-Conditioning and Refrigeration Center (ACRC) with 30 industrial sponsors. He received his Ph.D. from Purdue University (1989) and is widely known for his research on microscale heat transfer (he is co-author of the 3-zone flow boiling model with J.R. Thome). He is a leading world expert on air-side heat transfer in compact heat exchangers. His lectures will focus on air-side heat transfer of compact heat exchangers, including the best prediction methods for heat transfer and pressure drop, flow visualization results, heat transfer enhancement and evaluation methods, frost formation and condensate retention effects, and emerging methods to manage condensate during simultaneous heat and mass transfer.

COURSE LOCATION AND TRAVEL INFORMATION
(The location of the EPFL lecture room will be sent by e-mail before the course)

The course will be held on the campus of the Swiss Federal Institute of Technology Lausanne (EPFL) located in Lausanne, Switzerland (see website at www.epfl.ch for information on the university, site maps, road maps, etc.). The course will be held in building BM in lecture room BM5202. This building is on the center square of the EPFL campus and class room is on the 5th floor, accessable by elevator). Please see the map of the EPFL (showing where to walk in orange to arrive at the building BM) and a diagram of the building BM indicating the class room. The EPFL website also allows you to input the class room number and print out a map indicating its location on campus. Participants should arrive in time for the registration period on Monday beginning at 12:30.

Lausanne is easily reached within Europe by train (see website of Swiss railroad www.cff.ch for train schedules to/from Lausanne), by air (nearest airport is Geneva and this airport has direct trains to Lausanne, about 4 per hour of 50 minute duration, see previous website for schedules) and by car. The EPFL is easily reached (see attached map) by the TSOL tram line from the city center (get on at FLON and get off at EPFL stop - the black-red-white dot…do not get off at the UNIL stops!). This tram departs about every 8 minutes and takes about 15 minutes from the city center to the EPFL stop (purchase ticket on platform from machine before boarding the tram or at the ticket office at FLON). Obtain information to get to the FLON station at your hotel. If you reside in a hotel in Ouchy (part of Lausanne on Lake Geneva), you will need to take a Metrobus to the city center to reach FLON (your hotel can give you information). Limited parking (paid) at the EPFL is available in an underground garage (follow signs from main entrance)…recommend arriving by tram or taxi. The Lausanne city website is available at www.lausanne-tourisme.ch
