Abstract
The numerical simulation was carried out to investigate the effect of the blade fence with different height and different spanwise location on the secondary flow in compressor cascade composed of conventional straight blades. The results show that higher fence will block the spanwise flow better; the counter-rotating fence vortex formation has a close relation with the intensity of spanwise flow. The height of optimal fence, which is located one endwall boundary layer thickness away from the endwall, is equal to the inlet blade boundary layer thickness.
