Prof. John K. Kaldellis holds a Mechanical Engineering degree from the National Technical University of Athens (NTUA) and a Business Administration Diploma from the University of Piraeus. He obtained his PhD from NTUA (Fluid Sector) sponsored by Snecma-Dassault, France, and the Bodossakis Foundation, Greece. He is currently the head of the Mechanical Engineering Department and the director of the Soft Energy Applications and Environmental Protection Laboratory of the Technological Education Institute (TEI) of Piraeus. Professor Kaldellis is also the scientific director (for TEI of Piraeus) of the MSc in energy program organized by Heriot-Watt University and TEI of Piraeus. His research interests include feasibility analysis of energy sector applications, technological progress in the wind, hydro and solar energy markets, hybrid energy systems, energy storage issues, social attitudes toward renewable energy applications, and environmental technology atmospheric pollution. He has participated in numerous research projects funded by the European Union, European/Greek industries, and the Greek State. Professor Kaldellis has published six books concerning renewable energy applications and environmental protection. He is also the author of more than 100 scientific/research papers in international peer-reviewed journals and more than 300 papers in international scientific conferences. During the last decade, he has been a member of the Scientific Committee of the Hellenic Society of Mechanical–Electrical Engineers and of the organizing and scientific committees of several national and international conferences. He is currently Associate Editor (member of editorial board) of the Renewable Energy international journal and a reviewer in more than 40 international journals in the energy and environment sector. He is the editor of the Stand-Alone and Hybrid Wind Energy Systems: Technology, Energy Storage and Applications book that has been recently published.

N2 - Suitable techniques to convert country's wind availability (mostly in the low-speed regimes) as a kind of renewable energy source need to be scrutinized to achieve effective and efficient conversion. The Diffuser-Augmented Wind Turbine (DAWT) concept offers possibility to cope with such unfavorable situation. In this paper we describe efforts to step-up the potential power augmentation offerred by the DAWT. Modification of internal profile of the diffuser (based on Ohya's configuration without a flange) is done, i.e. by addding an optimized airfoil shape as interior profile of the diffuser. Additional velocity augmentation of 65.5% can be achieved in comparison to one with original flat interior.
