Thesis abstract
My PhD focuses on combustor-turbine interaction in gas turbines. Improving the understanding of this topic would increase gas turbines efficiency and reduce the noise production. I have carried out several experimental campaigns on a turbine test rig to study the impact of combustor non-uniformities on the turbine aerodynamics. At turbine inlet, engine-representative flow conditions are imposed through a novel combustor simulator able to combine a swirl profile and a steady or unsteady temperature disturbance. During a visiting period at the TU Berlin, I have studied the impact on noise emissions due to combustor-turbine interaction.
Personal interest in my research theme
What I like the most about my research field is its complexity and multidisciplinary. I have the opportunity to challenge myself and expand my knowledge in several fields that are not strictly related to the turbomachinery one. Furthermore, the energy transition to zero-carbon energy can not disregard an increase of the available technology efficiency. Therefore, I like my research because a better understanding of combustor-turbine interaction will reduce pollutants emission and aircrafts noise pollution.
