Overview
The 13th International Conference on Simulation and
Experiments in Heat and Mass Transfer (Heat Transfer 2014) took place in
A Coruña, Spain organised by Lund University of Technology, Sweden and
Wessex Institute, UK, with the collaboration of the University of A
Coruña.
The Conference Chairmen were Prof Bengt Sunden, from Lund University
and Prof Carlos A Brebbia, Director of the Wessex Institute.
The Conference started in Portsmouth, UK in 1988, followed by Milan
(1992); Southampton (1994); Udine (1996); Krakow (1998); Madrid (2000);
Halkidiki (2002); Lisbon (2004); New Forest, UK, home of the Wessex
Institute (2006); Maribor (2008); Tallinn (2010) and Split (2012).
The objective of the series is to provide a forum for presentation
and discussion of advanced topics, new approaches and applications of
innovative computational methods and experimental measurements in heat
and mass transfer.
Heat transfer topics and related phenomena are commonly of a complex
nature and different mechanisms like heat conduction, convection,
turbulence, thermal radiation and phase change as well as chemical
reactions may occur simultaneously. Typical applications are found in
heat exchanges, gas turbine cooling, turbulent combustion and fires,
fuel cells, batteries, micro- and mini- channels, electronic cooling,
melting and solidification, chemical processing and aerospace
engineering.
Heat transfer may be regarded as an established and mature scientific
discipline, but it plays a major role in new emerging ideas such as
sustainable development and reduction of greenhouse gases as well as for
micro- and nano-scale structures, nano fluids and bio-engineering.
Non-linear phenomena may occur due to temperature dependent
thermophysical properties.
To analyse the thermal process and enable design and optimisation,
advances in computational methods continue to be important as
engineering design and development require reliable and accurate
computational tools to replace or complement expensive and time
consuming experimental trial and error work. Tremendous advancements
have been achieved during recent years due to improved numerical
solution algorithms for non-linear differential equations, turbulence
modelling and the development of computers and computing programmes to
achieve efficient and rapid simulations. Nevertheless, further progress
in computational methods will require developments in theoretical and
predictive procedures in applied research. Accurate experimental
investigations with advanced instrumentation are needed to validate the
numerical calculations.
Many excellent research topics were discussed at the Heat Transfer
2014 conference, during which new applications were presented related to
the use of advanced computational methods and experimental measurements
in heat and mass transfer.
The Conference books containing papers presented at the meeting is
Volume 83 of the series WIT Transactions on Engineering Sciences, which
is widely distributed around the world in digital as well as hard copy
formats. The papers are also permanently archived in the Institute
eLibrary (http://library.witpress.com/), where they are easily accessible to the international community.
Opening of the Conference
The Conference was opened by Prof Carlos A Brebbia who explained the
work of the Wessex Institute, in particular its objective to act as a
mechanism for knowledge transfer. WIT – Carlos said – carries out this
by a series of activities, including industrial research, publication
and training.
In the field of industrial applications the Institute is renowned
throughout the world because of its pioneering research on boundary
elements. The method is used for the analysis of problems affecting
electric conduction and offshore structures and other situations used in
petroleum engineering. This allows for the design of effective cathodic
protection systems against corrosion. The efficient analysis of these
systems, Carlos explained, has been possible because of the development
of BEM tools.
Fracture mechanics and in particular crack propagation is another
problem in which the Institute has carried out original research using
BEM. The development of meshes that can follow the growth of cracks
allowed for the prediction of the residual life of components with
initial cracks. This has important applications in aerospace
engineering.
The international WIT conference programme is well known. It consists
of 25 or so meetings per year in different locations around the world.
The conferences aim to provide the right environment for the exchange of
scientific knowledge, promoting discussion and allowing for networking.
The conference papers are published in book form and widely distributed
throughout the world.
Training activities, including PhD and Post-doctoral research, takes
place in the Wessex Institute campus located in the New Forest, a
National Park in the South of England. The excellent facilities and the
peaceful environment render the campus an ideal place for research.
Carlos concluded his remarks by thanking the delegates for their
support of WIT conferences and hoping that they will consider visiting
the Institute campus, when convenient. In that way they will be able to
better appreciate the work of the Wessex Institute.
Keynote Address and Invited Presentations
The keynote address of the conference was delivered by Prof Sunden,
who spoke about “Computational opportunities of energy related transport
processes”. His talk was followed with great interest and gave rise to
numerous questions.
This was followed by an invited presentation by Prof Hussain
Al-Kayiem from Petronas University of Technology in Malaysia. The title
was “Ribbed double pipe heat exchanger experimental analysis”.

Special Talk
A special talk was given by Prof Hussain Al-Kayiem of the University
of Technology Petronas in Malaysia on the general topic of fluid dynamic
developments through aviation history.
He referred to the interesting history of Abbas Ibn Firnas, the first
man who attempted to fly in the ninth century. He built a glider that
has recently been replicated in the USA. Firnas was from Cordoba, Spain,
then a cultural centre as important as Damascus. He was an astronomer,
musician, mathematician and poet in his 70th year of age when he flew.
In the XI Century, Elmer in present day Iraq, also tried to fly and
much later Ahmed Celebi in the early 1800s glided from one side to the
other of the Bosphorus, inspired by the drawings of Leonardo da Vinci.
Also in the 19th century a series of German aviators contributed to the development of gliding.
It was the Wright brothers who set up the fundamentals of modern
aviation, applying scientific principles and developing ways to deal
with control and stability.
Hussain described the tests of these early pioneers who set up the
foundations of modern aviation with numerous illustrations and
photographs.
Social Occasions
The Conference offered the delegates numerous opportunities for
informal discussions outside the sessions, including coffee breaks,
complimentary lunches and the conference banquet.
The banquet took place in a restaurant renowned for the quality of
its Galician cuisine. The starter was octopus, before the main course,
consisting of veal marinated in red wine, followed by a dish of
different types of sweets and ice cream.
At the beginning of the dinner Carlos proposed a toast to all
conference participants and, in particular, to his Co-chairs, to whom
the success of the meeting was in great part due. He also explained the
unique culture and traditions of Galicia, derived from its Celtic roots.
At the end of the meal Carlos introduced a Galician musical ensemble.
They played a series of classical pieces from the region to the delight
and surprise of most of the audience. The Galician bagpipes are more
melodious than others and their music is always present in every
celebration or family events.
The International Scientific Advisory Committee (ISAC) met over
dinner to discuss the progress of the meeting and how to improve it in
2016 when it is to be reconvened. There were a few new topics suggested
as well as new members for the committee. The problems of visa
requirements in certain locations were a deterrent to hold the meeting
there. Some suggested locations were deemed better than others and they
will be investigated by the Conference Division at WIT.
