Experimental Aerodynamics and Propulsion Lab
The research activities focus on both advancement / development of current/new flow diagnostics techniques, data-driven methods and on the experimental investigation of vortical features, heat transport and mixing in complex flows. The experimental activities are prevalently targeted to aerospace propulsion-related aspects such as swirling flows and turbomachinery cooling.

Research lines
Advanced flow diagnostics
We work on the development and improvement of measurement tools for turbulent and complex flows. Our contributions have been mostly in the field of PIV (planar, stereoscopic and volumetric) and IR thermography. Recent efforts include the application of data-driven methods to improve measurement spatial and temporal resolution and signal-to-noise ratio.
Data-driven fluid mechanics
We investigate on data-driven tools to analyze numerical and experimental data. The tools we employ are aimed at flow sensing, model order reduction and control. Current activities include the sensing of large-scale motions in turbulent boundary layers and the heat transfer enhancement with closed loop control.
Wall-bounded turbulence
Turbulent boundary layers (TBLs) are of paramount importance given their ubiquitous presence in many relevant fluid-flow problems such as the flow over wings, land and sea vehicles, turbines, compressors, etc. The focus of our research is on the coherent structures organization, modeling and manipulation in canonical (pipe flows, ZPG TBLs) and non-canonical conditions.
Convective heat transfer
Convective heat transfer is relevant in countless industrial applications (turbomachinery, manufacturing, food processing, etc.). We use optical methods and data-mining techniques to investigate the flow feataures which are more intensively active in convective heat transfer phenomena.
