Abstract

•Tip clearance and axial gap of a multistage compressor is investigated through CFD.•Good agreement is found between CFD and experimental data.•Tip clearance has detrimental effect on turbine performance.•Upstream stator should be as close as possible to the rotor to improve performance.•Performance is unaffected by varying axial gap between rotor and downstream stator.
