The Laboratory of Fluid Mechanics & Turbomachinery (LFMT) was established in 1985 and it is part of the Energy Department of the School of Mechanical Engineering, Aristotle University of Thessaloniki. The facilities of LFMT cover an area of 400m2 (laboratory and office facilities).

The LFMT laboratory infrastructures include high and low speed wind tunnels of both open and close type, for high-quality experimental flow and heat transfer measurements on wings, turbomachinery blades (stationary or moving), heat exchangers and various other flow devices models. LFMT is equipped with high accuracy measurement instruments, such as Laser Doppler and Hot-wire anemometry, data acquisitions and analysis systems, especially for turbulent flows where cross- and auto-correlations are of high importance. LFMT is specialized on measurements for transitional flows on flat plates, wings and blades. Recently, LFMT has initiated the construction of a test-rig for noise measurements. LFMT is equipped with CPU power capable of massive computations for the numerical modeling of complex flow problems. LFMT has two clusters of 22 and 16 processors for High Performance Computing. LFMT has developed a full 3D Navier-Stokes parallelized and vectorized computer code for the solution of incompressible, compressible (up to M=6) laminar or turbulent flow problems, incorporating the most advanced Reynolds-stress turbulence models and all the eddy-viscosity models, linear and non-linear, used by the aeronautics industry. Currently, LFMT has started developing an in-house code for Large Eddy Simulation. LFMT has also licenses for the most modern commercial CFD software for the simulation of industrial flow problems.

The main scientific research effort of LFMT is focused on the transitional flows, heat transfer and flow development in heat exchangers, flow development in turbine blades, flow control of Delta wings and conventional wings, development of turbulence models, innovative aircraft engine cycles, noise control in aero engines and hybrid power generation plants.

The scientific research work of LFMT has been published in the highest quality International Journals on Fluid Mechanics and Turbomachinery such as the International Journal of Heat and Fluid Flow, Journal of Applied Thermal Engineering, AIAA Journal, Journal of Fluid Mechanics among others, while it has a constant presence in European and International Conferences such as the ASME – Turbo Expo Conference, the European Turbomachinery Conference and others. In 2010, LFMT has organized with a great success, the 7th Panhellenic Conference on Fluid Mechanics.

Since 1998, LFMT is developing, in cooperation with MTU Aero Engines GmbH, a deep experience in heat exchangers for recuperation installations inside aero engines. The role of LFMT is focused on the installation redesign of an MTU patent of a specific type heat exchanger for the minimization of the pressure losses and the optimization of the heat transfer inside the hot-gas exhaust nozzles of future novel aero engines.

LFMT has been participated in large European R&D projects, the majority of them co-founded by the major players in the international aeronautics industry such as MTU Aero Engines GmbH, Rolls-Royce plc, SNECMA, VOLVO Aero, Rolls-Royce DE. The majority of these projects has an averaged total budget more than 80M€, while the LFMT averaged 4-year budget for each project is about 800k€. Currently (2010), LFMT is participating in the 6th FP NEWAC and DREAM projects for the design of novel aero engines regarding the achievement of low-emissions and high engine performance based on the ACARE rules for the future engines for a green environment. Recently, after MTU’s invitation, LFMT became the only Greek Laboratory, among 36 partners, participating in a project proposal named LEMCOTEC with all the major European Aero Engine manufactures, for the design, construction and demonstration of a novel aero engine that will be used in flight operation in 2020.

LFMT became a recognized close-partner of MTU Aero Engines GmbH for the research on the thermal recuperation technology for aero engines.

LFMT is a member of the following international networks:

• ERCOFTAC – European Research Community On Flow Turbulence And Combustion

• EASN – European Aeronautics Scientific Network
