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.

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

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
