Aristotle University THessaloniki

Expertise and experience of the organization
The Laboratory of Heat Transfer and Environmental Engineering (LHTEE) belongs to the Energy Section of the Mechanical Engineering Department of AUTH. It has a long record of research and consulting activities, both at national and international level. Most of the research funds of the Laboratory originate from competitive programmes of the European Commission. In the last years, the total annual turnover of the Laboratory has been of the order of 1 million €. The Laboratory has significant experience and expertise in meteorological and air quality modelling and air quality assessment. The Laboratory’s research work focuses on the simulation of transport and chemical transformation of pollutants in the atmosphere with the use of advanced air quality models, with main focus lately on the urban air quality assessment. The Laboratory is also involved in Air Quality Management through the assessment of various measures for reducing air pollution levels, and the analysis of the impact of industrial activities and major public works on air quality. The Laboratory also provides practical support to public authorities and the private sector within this area of activities through the development of integrated environmental assessment tools with the use of informatics technologies. In the frame of its consulting services, LHTEE is also significantly involved in the various activities of EEA's European Topic Centre on Air and Climate Change.

Role and contribution

AUTH will co-ordinate WP4 and will play a significant role in WP2 and WP7. In WP4, AUTH will lead the investigation and testing of advanced physical and chemical parameterisations developed in WP2, and will describe the dispersion, transformation and removal processes of the pollutants across the mesoscale and urban scales. The coupled MEMO/MARS modelling system will also be used to relate meteorological patterns to urban air pollution episodes and to identify and quantify the contribution of the main local emission sources to the urban air quality. In WP2, numerical RANS and LES CFD simulations will be performed by AUTH for the systematic study of small-scale features in the urban canopy and their effect on the air flow, as well as for the description of the urban energy balance. In WP7, simplified approaches for assessing megacities impact and climate impact on megacities will be suggested, through defining a hierarchy of model complexities that will be organised with respect to the necessary input data, based on the implementation of the model systems for different megacities.

Principal personnel involved
Prof. Nicolas Moussiopoulos - Director of LHTEE, and a Full Prof. at AUTH; also an Honorary Prof. at the School of Mechanical Engineering (Universitaet Karlsruhe). His research focuses among others on the development of atmospheric wind and dispersion/chemistry models and their application at the local-to-regional scales. He co-ordinated several large international research projects and is the author of more than 300 scientific publications (more than 80 in peer-reviewed journals). He is currently actively involved in ACCENT, the European Network of Excellence on Atmospheric Composition Change, and in EU-funded projects such as CAIR4HEALTH and NEEDS. He is a member of the German Academy of Natural Scientists Leopoldina and in 2002 he was awarded the Order of Merit of the Federal Republic of Germany.
Mr. John Douros is a Res. Assoc. within LHTEE. He studied Physics at AUTH and Environmental Technology at Imperial College of the University of London where he completed his MSc course on fugitive dust dispersion modelling.  In 2001 he joined LHTEE where he is currently working on mesoscale meteorological modelling and photochemical dispersion modelling. He also participates in various EU-funded projects dealing with air pollution modelling and assessment, such as CAIR4HEALTH and NEEDS.
Mr. Photios Barmpas graduated as an Aerospace Engineer in 1997 and received M.Sc in Applied Mathematics and Fluid Mechanics in 1999 from the University of Manchester. Since then he has held a research engineering positioning LHTEE, in the field of CFD and Heat Transfer where he has registered as a PhD student. He has worked on the optimisation of heat exchangers in future commercial airliners aero-engines through CFD analysis as well as on wind flow and dispersion of pollutants in built-up areas for various EU projects. At the moment he is working on the investigation of wind flow and the dispersion of pollutants in built up areas using wind tunnel modelling techniques.
