ABSTRACT

The necessity to be compliant to worldwide legislation in increasingly demanding CO2 reduction leads to improvements in ICEs power and efficiency. Therefore, recently the attention has been shifted on engine cycle modification, stochiometric combustion and on the increase of temperatures at turbine inlet of the turbocharging units.

In this presentation, the results of an experimental campaign, performed to check turbine wheel temperatures during real engine applications, will be discussed together with a description of the experimental setup.

These maps were employed to improve mathematical CFD models, which are the roots of a life assessment model that can track turbocharger health in real time, extending traditional operating ranges and improving overall engine efficiency.

SPEAKER BIOGRAPHY

Silvio Rabbolini is a mechanical engineer at Ferrari. He received a Ph.D in machine design from Politecnico di Milano in 2015, focusing on fatigue life assessment of high temperature alloys. He has worked in the field of turbomachinery design for over 15 years, mainly focusing on fatigue life assessment of rotors and vessels, together with rotordynamics. He joined Ferrari in 2019, where he is currently developing turbocharging systems for GT applications.
