Energy Technology Group (ERGO)


Description of the research Group

The research activity of the group is focused on the study, analysis and design of components and systems for the energy conversion,  aiming at the improvment of the efficiency and the reduction of costs and environmental impact. To this purpose, we develope computational fluid dynamics codes, that  we apply to  the study and design of turbomachinery and we utilize commercial softwares for the simulation and optimization of processes related to the energy conversion.

Our researches are supported by experimental studies carried out within the Energy Systems Laboratory, mainly dedicated to the evaluation of the thermodynamic properties and thermal stability of working fluids and mixtures for innovative Organic Rankine Cycles engines.

The main research activities of the group are related to the following topics: Thermal engines and energy conversion systems, turbomachinery, innovative in-house codes for computational fluid dynamics, technologies for sustainable mobility.
