Overview

Numerical simulations reveal pivotal roles of tip secondary vortex in compressor stall dynamics, suggesting advanced diagnostics methods.

Key Points

  • Stall initiation is driven by tip secondary vortices, leading to significant backflow and vortex shedding.
  • The interaction between upstream and downstream TSVs creates leading-edge spillage, causing stall spikes.
  • Reduced-order variational mode decomposition enables effective flow structure extraction, addressing data complexity.
  • Parameter optimization remains a challenge, affecting the reliability of flow characteristic analysis.
