摘要：
Both numerical and experimental investigations were carried out to study the effect of aerodynamic sweeping-curving on the endwall flow field of compressor cascade. The precision of the numerical simulation depends on the inlet and outlet boundary conditions as well as the turbulence model more than the grid refinement level and the grid type. The 3-D flow field is changed completely in a forward-swept compressor cascade, which makes the low energy fluid redistribute in the flow passage. The blade both with positively curving and forward sweeping further strengthens this kind of effect, providing a freedom to the blade design.
