In this research, An investigation is done to understand the effects of blades surface roughness on the Transonic 4-stageAxial compressor performance parameters. A CFD code, which solves the Reynolds-averaged Navier–Stokes equations, was used to simulate the complicated 3D flow field of the Axial compressor. Numerical results was validated against experimental data of the Axial compressor performance curves. Numerical data showed good agreement with experimental data. Then, the effects of blades surface roughness on the Axial compressor performance parameters at design point was analyzed. Results show that blades surface roughness leads to increase boundary layers and pressure loss and decrease the efficiency and pressure ratio. So efficiency reduction goes up comparing with pressure ratio in the compressor.
