Diagnosis and Analysis of Interstage Flow Field in a High Load Compressor

This article conducted flow field refinement tests on a high load compressor using steady-state five hole probes, high-frequency dynamic probes, and blade probes, and obtained detailed inter stage flow field characteristics such as total pressure, total temperature, and Mach number. The results showed that by analyzing and comparing the flow field parameters of the compressor’s overall performance and inter stage performance tests with CFD design performance, the main characteristics that affect compressor performance can be effectively obtained, Obtain the flow field performance of the blade near the end wall and upstream and downstream blades, among which the steady-state five hole probe and dynamic single hole probe effectively overcome the problem of limited conventional measurement space for the compressor; The blade probe obtained detailed flow field distributions of performance parameters along the radial and circumferential directions of the 1–3 stage rotor, providing experimental data support for compressor flow field diagnosis and performance optimization.
