FUNDAMENTALS OF MICROSCALE
HEAT TRANSFER:
BOILING, CONDENSATION,
SINGLE- AND
TWO-PHASE FLOWS
A Five Day Short Course in Lausanne, Switzerland
(June 3-7,
2013)
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 four
books and
received the ASME Heat Transfer Division's Best Paper Award in
1998 for
his work on flow boiling heat transfer, the UK IOR J&E
Hall Gold
Medal (2008) for his work on refrigeration heat transfer, and
the ASME Heat Transfer Memorial Award for his microscale
two-phase heat transfer research. 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.

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

COURSE LOCATION
AND
TRAVEL INFORMATION
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 BC in the meeting room BC 02 indicating
the building BC and
the class room. To
locate and print a map of campus
with the room and building BC, go here.
Please see the map1
of
the EPFL (showing also the metro stop).
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 map2) 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 need to take a tram from the Ouchy
station to get to 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
