Background:

  • Rotating-disc systems are crucial for modeling gas-turbine engine cooling-air systems.
  • Understanding flow and heat transfer in these systems is vital for engine efficiency and longevity.

Purpose of the Study:

  • To review recent computational and experimental research on three key rotating-disc systems.
  • To discuss challenges and findings related to pre-swirl systems, rotating cavities with peripheral flow, and buoyancy-induced flow.
  • To present heat transfer results for sealed annuli and rotating cavities with axial throughflow.

Main Methods:

  • Review of computational fluid dynamics (CFD) research.
  • Analysis of experimental data.
  • Comparison of different rotating-disc system configurations.
