The overall mission of the Laboratory of Applied Thermodynamics and Statistical Mechanics (LAT) is to deliver high quality education and research in the fields of Thermodynamics, Transport Phenomena and Combustion, with particular regard to their applications.

LAT has established partnerships within European Academic and Research Associations aiming to advance teaching as well as scientific knowledge and technology. LAT is a member of the European Research Community on Flow, Turbulence and Combustion (ERCOFTAC), the European Aeronautics Science Network Association (EASN) and the Greek Section of the Combustion Institute. The Lab is participating in a large number of national and European research projects. LAT is partner in the EU NoE on Environmentally Compatible Air Transport System (ECATS).

The experimental and numerical capabilities of LAT are used to provide services and consultancy in the fields of thermo-fluids and combustion. LAT is also accredited to carry out tests under the terms of ISO/IEC 17025. LAT, in collaboration with EADS, holds a patent on microtechnology manufacturing of multi sensor hot wire anemometry probes.

Teaching

Educational activities of the Laboratory of Applied Thermodynamics cover areas in Thermo-fluids, such as Thermodynamics, Transport Phenomena of mass, momentum and heat in ordinary and multiphase systems, Combustion and Propulsion by offering a number of courses in these subjects.

Undergraduate courses:

· Thermodynamics I, Thermodynamics II

· Heat Transfer II

· Internal Combustion Engines

· Transport Phenomena

· Combustion and Pollutants

· Gas and Steam Turbines

· Advanced Heat and Mass Transfer

· Theory and Modeling of Turbulence Flows

· Aerospace Propulsion Systems

Postgraduate courses

· Thermal Energy on the Generation of Work

· Phenomena on Turbulent Transfer Flow

· Experimental techniques in Transport Phenomena

During the last 20 years more than 100 diploma dissertations and 20 doctoral theses have been completed successfully

Research

 

Research activities at LAT cover the areas of Heat Transfer, Fluid Mechanics, Multi Phase Flows-Spray dynamics and Combustion, with application in the fields of Energy, the Environment, Aeronautics and Biotechnology. Research is mostly financed by the EC, but also by the industry and National Research supporting agencies.
