The comparison of the computational results of real gas model with that of perfect gas model shows that it is very important to apply the real gas model in the numerical simulations, and also the real gas model presented shows itself more profitable and applicable in numerical applications.

Fence vortex, which more to the middle of the cascade passage, reduce the loss near the middle of the cascade.

吸力面翼刀通过阻断气流的展向流动和产生反向翼刀涡来对栅内二次流动进行控制。

It is indicated that this loss will not change with the increase of the Reynolds number but the intensity of the passage vortex increases with the decrease of the Reynolds number. The tip leakage flow will weaken with the increase of the passage vortex because of the interaction between the passage vortex and the tip leakage vortex, and the position of the tip leakage vortex is more close to the middle of the passage. In addition, the distributions of the total pressure loss and the flow angle at the exit of the cascade are influenced by the intensity and the position of the tip leakage vortex.

结果表明：对于间隙存在造成的流动损失，数值模拟结果与实验结果及 Denton的预测值都十分接近，基本上不随着雷诺数的变化而变化；但是，随着雷诺数的减小，通道涡增强；间隙泄漏涡在和通道涡的相互作用中，强度减弱，在叶栅出口处的位置更加靠近中叶展；出口处的总压损失和气流角的分布也由于间隙泄漏涡强度和位置的变化而发生改变。

On the basis of it, the cascade flow field with endwall suction, the effects of suction on the different endwall locations (such as near the leading-edge, in the middle of the passage or near the suction surface) on the development of secondary flow, the distributions of total pressure loss coefficient and yaw angle are investigated respectively.
