This paper presents the numerical prediction for an inviscid , rotational and compressible flow in a two-dimensional curved duct with inlet total pressure distortion. The numerical method is a fully implicit finite difference technique solving the unsteady form of the continuity, Euler equations and the steady form of the energy equation. The results are presented for different cases of inlet total pressure distortion with the same average total pressure for all cases. These results are compared with those obtained from uniform inlet total pressure distribution to assess the deviation resulting from the uniform total pressure assumption.
