Heat Transfer 2012
12th International Conference on Simulation and Experiments in Heat Transfer and their Applications
27 - 29 June 2012
The 12th International Conference on Advanced Computational Methods and Experiments in Heat Transfer has recently taken place in Split, co-organised by Prof Bengt Sunden of University of Lund, Sweden; Prof Carlos A Brebbia of Wessex Institute of Technology, UK and Prof Dragan Poljak of the University of Split, Croatia.
Advances of computational methods for solving and understanding heat transfer problems continue to be important because 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. Typically, applications are found in heat exchanges, gas turbine cooling, turbulent combustions and fires, fuel cells, batteries, micro and macro channels, electronics cooling; melting and solidification, chemical processing etc. Heat transfer might be regarded as an established and mature scientific discipline, but it has played a major role in new emerging areas such as sustainable development and reduction of greenhouse gases, as well as for micro- and nano-structures and bio-engineering. Non-linear phenomena other than momentum transfer may occur due to temperature dependent thermophysical properties. In engineering design and development, reliable and accurate computational methods are required to replace and complement expensive and time consuming experimental trial and error work. Tremendous advancements have been achieved during recent years due to improved measurement simulation methods for non-linear partial differential equations turbulence modelling advances and development of computer and computing algorithms to achieve efficient and rapid calculations. Nevertheless, to further progress in computational methods will require developments in the theoretical and numerical fields.
Many relevant research topics were discussed during the twelfth international conference on Advanced Computational Methods and Experimental Measurements in Heat Transfer and Mass Transfer. The objectives of the conference series is to provide a forum for the presentation and discussion of advanced topics, new approaches and application of advanced computational methods and experimental measurements to heat and mass transfer as well as other transport phenomena.
Special SessionA special session took place to welcome the delegates to Split. It comprised of a series of addresses by academic and government authorities.
Prof Carlos A Brebbia opened the proceedings by pointing out the important results being obtained from the existing link between the University of Split and his Wessex Institute of Technology. The link between the two institutions started 15 or so years ago and began with a number of joint conferences, on a range of topics related to advances in computational methods. This collaboration resulted in three meetings held in Split in 2012, (ie Boundary Element and other Mesh Reduction Methods; Advances in Fluid Mechanics and Heat Transfer). Previous meetings took place in the Split region, including a conference on the island of Brac. Recently, Carlos pointed out, two important conferences were held at the University Institute in Dubrovnik, another beautiful location in Croatia.
Collaboration between WIT and the University of Split – Carlos said – has provided other outstanding results. The two institutions ran a Master course for a period of five years graduating in the process a substantial number of candidates, who contributed a series of outstanding final dissertations. Several of them continued their studies and have now obtained a PhD degree from the University of Wales, the validating authority of WIT.
Many papers in learned journals bear witness to the fruitful links between the two Institutions, and are the result of research collaboration. In addition, WIT Press, the publishing arm of the Wessex Institute, has published several books authored by Split researchers, including some major works by Dragan Poljak on the topic of electromagnetism, EM radiation problems and their effects on human health.
Carlos hoped that his Institute will be able to continue to strengthen its working relationship with the University of Split as well as Croatian industry and other government organisations in the region.
WIT is for instance planning some joint initiatives with the Croatian Hydrodynamics Institute, including a conference on Island Sustainability (see http://www.wessex.ac.uk/12-conferences/islands-2012.html).
Carlos ended his address by thanking the University and the City of Split as well as the county for the warm hospitality that delegates from all over the world have received in this unique part of the Mediterranean.The next speaker was Prof Dragan Poljak who pointed out the rapid development that took place in Split and particularly at the University. The Faculty of Engineering, where he works, has continued to grow and is now one of the best Schools of Engineering in Europe, particularly in topics related to his own Department of Electrical Engineering. The number of engineering fields covered by the School has increased and they are keen to strengthen their research links by interacting with other institutions.
The philosophy of the School – Dragan said – is towards commercialisation, innovation and interacting with other institutions.
The next speaker was Professor Srojan Podrug, Dean of the Faculty of Engineering at the University of Split, who described in detail the different areas of interest in their Faculty and the research being carried out. This was followed by the welcoming address of Professor Tomisav Kilic, Vice Rector of the University, who referred to the considerable growth that the Institution underwent in the last few years.
Mr Vikko Havidič, Vice Governor of the county of Split, Dalmatia, mentioned the expansion plans to take place in the near future and their targets for technological development; a topic that was also included in the following address by Mr Ivan Vestič, Senior Councillor for the City of Split.
Book LaunchFollowing the above addresses Carlos closed the session with the launching of the newly published book by Bengt Sunden, ‘Introduction to Heat Transfer’ (ISBN 978-1-84564-656-1, 2012 WIT Press).
Carlos described first the scientific career of Bengt who completed his education at the renowned Chalmers University of Technology in Göteburg (MSc in Mechanical Engineering 1973, PhD in 1979 and Free Docent in 1980).
Since then he worked at Lund University, where he became a Full Professor of Heat Transfer in 1993. He is currently Head of the Department of Engineering Sciences.
His research contributions span a large number of topics as testified by the Development in Heat Transfer book series that he has been editing for WIT Press since 1995.
He is or has been editor of renowned journals and received several medals and awards, including the ASME Heat Transfer Memorial Award, and the Wessex Institute of Technology Eminent Scientist Medal.
The new book represents his achievements as a teacher and will be a most valuable learning tool for many emerging generations.
The conference discussed a series of important topics with the papers grouped together in the following sessions:
- Heat transfer in energy production
- Heat transfer problems
- Natural and forced convection and radiation
- Multiple flow heat transfer
- Modelling and experiments

Tour and Conference DinnerThe University of Split offered a guided tour of the Diocletian Palace and the old town, followed by a reception, where a series of local specialities were offered.
There was first a guided tour of the surrounding areas of the city, describing some of the most prominent sites, its archaeological and historical past and the beautiful parks, beaches, promenades all along the coast. After this they were shown the most important sites within the Diocletian Emperor’s Palace, whose massive structure is largely intact and gives shelter to a whole range of shops, restaurants, apartments and even churches, the most spectacular of which is the Saint Dominic basilique built upon the foundations of the Emperor’s tomb. In this manner Christianity, a religion that Diocles persecuted, was to triumph over the pagan Emperor. At the end of the tour the delegates were offered a reception in the vaults of the Palace after a recital given by a Choir singing Dalmatian pieces. The reception consisted of typical Croatian dishes and delicacies accompanied by excellent local wines. The event helped to cement even further the links between all participants.The Conference dinner took place in what is considered to be the best restaurant in town and the dishes consisted of an excellent starter, a nicely-cooked risotto, followed by a beef cut as main course. This was accompanied by excellent local wines. The evening was enhanced by a quintet that played international songs as well as a few Dalmatian pieces. The relaxed atmosphere and good company helped to cement the links between participants. The restaurant located on the sea front offered outstanding views of the sea and some of the islands facing Split.
The ISAC met over dinner to discuss reconvening the conference in 2014 and to discuss new topics to be included, as well as nominations for the Committee. The general consensus was to reconvene the meeting in Europe and several possible locations were proposed. WIT Conference Manager will investigate the possible sites and venues, aiming to find a balance between accessibility and involving local institutions wherever possible.
