Implication

Testing reveals seal clearance significantly influences aerodynamic performance and stall margin in compressors, indicating design adjustments are necessary.

Key Points

Seal clearance significantly impacts the stage's operating range and overall performance characteristics.
Testing with two distinct seal clearance sizes showed marked effects on aerodynamic performance and stall margin.
CFD simulations were supplemented to analyze the interaction of leakage flow from the seals with the primary flow dynamics.
Discussion emphasizes the necessity of integrating seal clearance effects during the design phase to optimize performance.
