Original publication title: Effect of blade parameters on radial turbine rotor aerodynamics.
Plain-English summary
This study looks at how different design features of radial turbines, which are important for turbochargers and compact power systems, affect their performance. The researchers used computer simulations to change factors like blade angle, thickness, and the number of blades to see how these changes impact efficiency and airflow. They found that by optimizing these design elements, they could improve how smoothly the air flows through the turbine and reduce energy losses. The results provide useful insights that can help in designing more efficient radial turbines in the future. Overall, the study shows that careful adjustments to turbine design can lead to better performance.
Abstract
Radial turbines play a vital role in turbochargers and compact power systems, where efficiency and size optimization are crucial. However, the combined aerodynamic effects of key rotor geometric features-namely blade angle distribution, thickness profile, and blade count-have not been comprehensively examined. This work presents a unified CFD-based methodology to assess how coordinated changes in these parameters influence turbine performance. A validated numerical model of a reference rotor was employed to systematically vary each design factor and evaluate its impact on efficiency and reduced mass flow. The investigation demonstrates that carefully optimized geometric adjustments can enhance flow uniformity, minimize secondary losses, and improve overall energy conversion. The study establishes clear performance trends supported by detailed flow-field analysis and provides design-oriented correlations that can guide future optimization of radial turbine rotors for high-efficiency operation.
