A Computational Fluid Dynamics (CFD) model was used to evaluate the thermal comfort conditions in the main indoor arenas and amphitheatres used in the Olympic Games “Athens 2004”. The CFD code was applied to calculate the 3-D airflow and temperature fields in the arenas and amphitheatres for various values of temperatures of conditioned inlet air (Tin). Calculated mean velocities and temperatures were used to determine the thermal comfort indices PMV (Predicted Mean Vote) and PPD (Predicted Percentage of Dissatisfied) and to evaluate the thermal conditions in the various regions of the arenas and amphitheatres. Calculated PMV and PPD values showed that thermal conditions in the arenas and amphitheatres were generally satisfactory for specific values of Tin; only a small percentage of the spectators were expected to be slightly uncomfortable.

Brief biography of the speaker:
Prof. Stamou is a Dr. Civil Eng. (NTUA), Dipl. Rural and Surveying Eng. (NTUA) with postgraduate studies in the Imperial College of Science and Technology and the University of Karlsruhe. His specialisation is "Computational Methods in Environmental Fluid Mechanics and in the Design of Relevant Hydraulic Works". He has a continuous 25-years experience of teaching, research and consulting in the development and application of mathematical models in applied hydraulics, environmental fluid mechanics and water management. He has participated in 42 research projects, in 23 of whish as a Project Leader (PL) and he has supervised over 70 diploma and PhD theses in the NTUA, University of Thessaly and other European Universities. He acted as a consultant and/or project manager in projects/studies for Ministries, Water Authorities, International Organisations, Consulting Companies, Multinational Companies, Construction Companies and the Technical Chamber of Greece. He has participated in over 105 engineering studies dealing with the following: (1) Environmental Impact Studies, environmental hydraulics and relevant works, such as sewage treatment plants, (2) development and application of mathematical models for: 3-D flows in complex hydraulic works, hydrodynamic behaviour and efficiency of water/wastewater treatment units, hydrodynamic circulation and water quality-pollution in surface waters (rivers, lakes, coastal waters, fisheries-aquacultures), propagation of waves, due to dam break, and (3) water management, e.g. water supply, drainage, wastewater transportation, storm water protection, irrigation etc.
