CREA Lab

CREA laboratory aims at being a centre of excellence for the study of fluid dynamics not suitable for applications in the field of renewable energies. The activity is mainly directed to new measurement techniques' development and to innovative fluid machines' design, with particular reference to turbomachines for organic fluid Rankine cycle (ORC) and for operating cycles with supercritical CO₂ (scCO₂). Thanks to the integration of different skills of the involved Departments, the laboratory is an authoritative point of reference, in the national and international scene, for industrial and academic partners.

Bovisa Campus of via La Masa (building B16A).

The Climate-lab laboratory possesses a network of instruments, some unmovable positioned in suitable sites at the Politecnico (permanent test sites), others positioned temporarily outdoors in particularly interesting study sites (temporary test sites).

• instrumentation for non-conventional measuring of variables and processes of interest in the context of climate change. Fine resolution measuring equipment of liquid precipitations, of river runoff and temperatures, of the snow cover's dynamics in mountainous areas
• measuring instruments (millimetre-wave and optical band devices) for evaluating the properties of atmospheric components (gas and precipitation)
• radiometric-type measuring instruments for evaluating the optical and radiation properties of surfaces
• stations for microclimate analysis and dynamics of green roofs in urban areas
• mobile analysers for measuring emissions and the concentration of pollutants

(*) Note: the TROVA installation is currently the only testing facility in the world where it is possible to observe optically a non-ideal organic fluid flow. Its realization, over the past six years, was primarily funded with funds from industry field, demonstrating that industrial world is interested on fluid dynamics studies of non-ideal flows.

CREA laboratory provides services for optical and pressure measurements in non-ideal fluid flows, in proximity of the liquid-vapor saturation curve. Pressure measurements are made with instruments calibrated for temperatures up to 300°C. Optical measurements are double-passage Schlieren and Laser Doppler Velocimetry (LDV) measurements.

CREA laboratory works in research projects under agreement with public and private bodies. The laboratory equipment is also available for third party activities. Methods and costs of single activities are evaluated and quantified upon request.
