Specialised in the experimental, numerical, modelling and the high-accuracy CFD study of turbine and compressor performance and their components.
The Fluid Dynamics of Machines (FLM) laboratory is dedicated to the experimental study and characterisation of fluid dynamic performance in turbomachinery and wind turbines. The lab has two wind tunnels equipped with high-frequency pressure probes, LDV systems and Schlieren systems for studying the flow field of turbomachinery. It supports the development of new blade profiles and turbomachinery elements from the early design stages.
Years of research and development have led to the creation of proprietary codes for the design and analysis of turbomachinery (mean-line and through-flow codes) and CFD codes for the simulation of two-phase flows and/or flows characterised by complex thermodynamic descriptions. Three-dimensional shape optimisation techniques based on surrogate models have also been developed, aimed at improving the aerodynamic performance of both the components studied and unconventional machines, for which there are no established design criteria.
Its experience and experimentation capabilities, together with its established expertise in the application of CFD codes, make LFM one of the leading laboratories in this field in Europe.
