Biography
My current research interests and activities are related to both numerical and experimental research on heat pumps, refrigeration systems and other energy cycles. The specific focus of the research activities is on cycle modelling and thermodynamics, refrigerants, heat recovery, turbomachinery (especially centrifugal machines), real gas modelling and CFD.
During my research career I have gained solid expertise in numerical and experimental work related to heat pumps, gas turbines, steam turbines, and energy systems adopting supercritical fluid states. One of the focus areas during my research career has been organic Rankine cycles (ORC) that are capable to convert heat into electricity. ORC process is based on the working principle of conventional steam Rankine process, but an organic working medium is adopted in the system.
