Laboratory of Fluid Mechanics and Turbomachinery


The Laboratory of Fluid Mechanics & Turbomachinery (LFMT) has been established in 1986. The laboratory offers to the students of the Department of Mechanical Engineering of Aristotle University of Thessaloniki, a number of lectures covering the topics of Fluid Mechanics, Turbulence Modeling, Aerodynamics, Turbomachinery, Aeronautics, Aero Engines, Measurement Techniques in Fluid Mechanics and Computational Fluid Dynamics. Since 1986, 19 PhDs have been awarded to post graduate students under the supervision of LFMT.

Flow measurements

I. Flow measurements

LFMT is equipped with a number of various closed and open type wind-tunnels for the measurements of fluid flow fields around scaled models of wings, airfoils, airplanes and other mechanical devices related to external flows. In addition a number of dedicated test rigs are available for internal flow measurements primarily focusing on heat exchanger applications, bearing chambers lubrication systems and turbine blade stator-rotor interaction.

The flow measurements are conducted with state of the art laser Doppler anemometry (3D-LDA) and hot-wire measurement systems supported by high accuracy moving mechanisms. The acquisition of the measurement data is performed with an in-house developed software in addition with other commercial software packages.

II. Computational resources - software

LFMT is equipped with three computer clusters (96cores, 22cores and 16cores) for massive parallel CFD simulations, using both in-house developed and commercial CFD codes (ANSYS FLUENT/CFX, NUMECA FINE). LFMT has also developed presizing tools for the conceptual design of aircrafts/UAVs and for the design of customized/novel heat exchanger and recuperation systems. Additionally, LFMT performs thermodynamic cycle analysis and optimization for the conceptual design of new aero engines with the use of dedicated commercial software (GasTurb). Finally, LFMT is capable of carrying-out noise propagation measurements and analysis supported by the NOISE LAB commercial software.

I. Fluid mechanics & aerodynamics
The fundamental research activities which are carried out by LFMT are focused on the experimental and computational investigation of transitional boundary layers and the development of sophisticated turbulence models including URANS, LES and DES. Additionally, the aerodynamic characteristics and the identification of vortical structures on Delta wings and blended wing bodies are investigated experimentally and computationally.


II. Turbomachinery
LFMT is performing experimental measurements and CFD computations regarding the investigation of the interaction of the wake and the boundary layer on turbine stator-rotor configurations. The investigation is focused on the identification and analysis of turbulence characteristics and coherent flow structures with Fast Fourier Transformation (FFT) and Proper Orthogonal Decomposition (POD) with commercial and in-house developed tools.


Since 1989, LFMT has participated in numerous funded research project in close collaboration with the European Industry in Aeronautics and Aero Engines. During the last 4 years, the total income for LFMT is 2.0M€. In the last 15 years, LFMT became a close partner of MTU Aero Engines AG in subjects related to the development of heat recuperation systems for aero engines having innovative thermodynamic cycle and design architectures. The main target of the research is focused on the reduction of fuel consumption and pollutant emissions for the aircraft engines that will operate after year 2050.

Apart from the aero engines industry, LFMT is very active in the applied research and development on a National level through strong collaborations with the Greek industry.

Through the years, LFMT became a strong and loyal partner of the European aero engines industry while it has developed collaborations with Greek companies in the National level. LFMT is among the 21 laboratories of the Aristotle University of Thessaloniki, which provide services in subjects related to the production/use of energy in mechanical systems. LFMT is included as a reference for the innovative Greek research academic laboratories in the site of the Ministry of the Environment, energy and climate change.
