This paper mainly investigates the effect of circumferential nonuniform tip clearance on the performance of compressors. Initially, three-dimensional full-annulus simulations are implemented based on a transonic fan with several different nonuniform clearance configurations. Then, the performance response to the nonuniform clearance is assessed by steady-state computations. According to the uniform cases, an engineering method is developed to estimate the performance of nonuniform tip clearance. Finally, experiments are carried out based on a single-stage, low-speed axial compressor to verify the effectiveness of our evaluation method. Performance curves can be well estimated both in numerical and experimental investigations. The engineering estimation method is applicable for nonuniform clearance cases.
