FUNDAMENTALS OF MICROSCALE HEAT
TRANSFER:
BOILING, CONDENSATION,
SINGLE- AND TWO-PHASE FLOWS
A Five Day Short Course in Lausanne, Switzerland (June
11-15, 2012)
Course Host: Heat Transfer Research Inc. (HTRI)
150 Venture Drive
College Station, Texas 77845, USA
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.

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.

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 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 CM and class room
is CM 0 11. This building is on the center square of the EPFL
campus, just behind
TechTravel go down the stairs. Please see the map1 of the EPFL
(showing also the metro stop) and a map2 indicating the building CM and 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 map3) 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
