| Abstract: | The effectiveness of a non-axisymmetric endwall on a high-load compressor cascade was discussed.First of all,the trigonometric function was used to complete non-axisymmetric endwall profiling.Then the method of calculating the mixed-out secondary loss for the compressor cascade was established.Finally,the detailed numerical simulations were conducted on the cascade flow field with non-axisymmetric hub endwall.Numerical results show that with the non-axisymmetric hub endwall,the loading distribution near the... |
