Discussion

Numerical simulations and wind tunnel tests reveal how tip clearance influences leakage flow and pressure loss in VIGV cascades.

Tip clearance variations significantly affect the aerodynamic performance metrics of VIGV cascades in centrifugal compressors.
At a ratio of 0.19Ma, total pressure loss coefficient (Cpt) increased by 10% with optimal 2.5% tip clearance before dropping by 30% at 10%.
Numerical simulation and wind tunnel validation were utilized to assess the impact of different tip clearances on airflow metrics.
Findings suggest potential improvements in compressor design by optimizing tip clearance for enhanced performance metrics.

Wang et al. (2025) studied this question.
