Overview

Randomized trial improves turbine efficiency in ORC systems, indicating enhanced performance and diagnostics.

Key Points

  • This study aims to improve the performance of radial inflow turbines in high-speed Organic Rankine Cycle systems through an innovative design approach.
  • Developed a physics-guided design integrating one-dimensional and three-dimensional optimization techniques.
  • Validated the model against experimental data of a baseline turbine.
  • Optimized three key geometric parameters under axial thrust and mass flow constraints.
  • Increased total-to-total isentropic efficiency from 74.7% to 87.1%.
  • Identified a negative correlation between volumetric average EGM parameter and turbine efficiency.
  • Demonstrated that better internal flow organization significantly enhances turbine performance.
