Fuelling Turbocharged Ideas: HPT at ISUAAAT-17
Researchers from KTH’s HPT turbomachinery group presented the most recent developments from their innovative research at the 17th International Symposium on Unsteady Aerodynamics, Aeroacoustics and Aeroelasticity of Turbomachines (ISUAAAT-17), held in Melbourne, Australia, from 17 - 21 November 2025.
ISUAAAT is a leading global forum for specialists in unsteady aerodynamics, aeroacoustics, and aeroelasticity. For more than 45 years, this five-day symposium has encouraged technical exchange and collaboration among experts and emerging researchers. This year’s event brought together over 150 participants from academia and industry worldwide.
The developments from three ongoing research projects at HPT were featured during the symposium:
Industrial PhD student Janakiraman Thiyagarajan presented his latest paper “A parameter to indicate centrifugal impeller exit BPF noise levels”. Developed within a KTH – Scania partnership, his work introduces a new design parameter – the Acoustic Crest Factor, that could predict centrifugal impeller exit Blade Pass Frequency (BPF) noise levels using RANS simulations.
Nenad Glodic shared insights from his research on the “Aeroelastic design of large-diameter composite fan blade”, conducted within a KTH and GKN Aerospace AB collaboration framework. His work demonstrates the potential of tailored composite carbon-fibre reinforced fan blades to improve aeroelastic stability when compared to reference metallic blades.
Mauricio Gutierrez also presented his paper on the “Impact of uncertainties on mistuned forced response predictions in a transonic compressor blisk”. His study combined experimental validation with advanced aerodynamic damping analysis to understand numerical uncertainties in the force response analysis for blisks.
Each presentation sparked lively discussions, reinforcing the significance of these advances in the future of turbomachinery.
