This study examines the significant influence of energy dynamics on axial compressor performance, particularly focusing on the axial spacing between the rotor and stator. Through numerical analysis utilizing CFD simulations with the ANSYS 19.0 R3 FLUENT software, we validate the impact of axial spacing on the performance of a single-stage compressor cascade. Our investigation specifically addresses the axial area between rotating and stationary blade rows in axial-flow compressors, emphasizing geometry and aerothermodynamic considerations. The analysis, conducted across various axial spacing (18%, 20%, 22%, and 24%), aims to optimize axial spacing for improved pressure rise and compressor cascade efficiency. Consequently, reducing the gap between the rotor and stator axial decreases compressor diffusion capacity, thereby enhancing cascade performance.

摘要

This study examines the significant influence of energy dynamics on axial compressor performance, particularly focusing on the axial spacing between the rotor and stator. Through numerical analysis utilizing CFD simulations with the ANSYS 19.0 R3 FLUENT software, we validate the impact of axial spacing on the performance of a single-stage compressor cascade. Our investigation specifically addresses the axial area between rotating and stationary blade rows in axial-flow compressors, emphasizing geometry and aerothermodynamic considerations. The analysis, conducted across various axial spacing (18%, 20%, 22%, and 24%), aims to optimize axial spacing for improved pressure rise and compressor cascade efficiency. Consequently, reducing the gap between the rotor and stator axial decreases compressor diffusion capacity, thereby enhancing cascade performance.
