- IGV influences the rotor passage with IGV wake and tip corner flow of IGV suction surface. 转子上游的导 叶通过导叶尾 迹和吸力面角涡对转子通道进行干涉。
- Backflow phenomena in the inlet of inducer and the flange clearance were described.The cause of pressure diffe-rence between suction surface and press surface was explained. 描述了诱导轮进口及轮缘间隙处的回流现象,解释了回流现象发生的原因,即轮缘处叶片压力面和吸力面存在压差;
- The spanwise movement and mixing of vortices on the blade suction surface towards the mid-span was stronger due to the effect of the increased positive bowed angle. 叶展中部流动分离的加重导致集中涡系破裂,从而引起流道内气流的严重堵塞,这是损失激增的主要原因,因此,要在高负荷压气机叶栅中应用正弯叶片,必须有效抑制中部流动的恶化。
- The photos of flow visualization show that corner vortex generates and develops near the suction surface of blade/endwall junction, which forms a triangle region. 流场显示图片说明:叶片吸力面靠近端壁有角涡形成与发展,并存在一个三角形区域;
- Time averaged temperature distributions on rotor surface will greatly change with the hot streak/airfoil ratio, and the temperature distribution changes more on the pressure surface than that on the suction surface of the rotor. 改变热斑数与导叶通道数比会对动叶时均温度分布产生较大影响,动叶压力面温度分布所受的影响更大。
- Secondary traverse flow velocity vector plots show the scrapping of the tip leakage vortex from the suction surface of one blade across the blade pitch to the pressure surface of the adjacent blade. 数值和实验结果均表明,端壁移动情况下间隙区域的二次流动特征是刮削泄漏涡的形成和发展。
