《ASME Journel of Turbomachinery》2011年1月刊叙述了利用轮廓成形端壁的好处,以及减少低压涡轮二次流损失的一种新流动机理。近年来,广泛应用轮廓成形端壁,更深入地了解了主流二次流减少的物理现象。基于此,重新设计了低压涡轮典型的实心薄叶型直列叶栅端壁的几何形状。提供了试验数据,证明这个 The January 2011 issue of ASME Journel of Turbomachinery describes the benefits of using profiled end walls and a new flow mechanism to reduce the secondary flow loss of low pressure turbines. In recent years, extensive use of contour forming end wall, a deeper understanding of the mainstream of the secondary flow to reduce the physical phenomenon. Based on this, the geometry of the end wall of a typical solid leaflet cascade of low pressure turbines has been redesigned. Provided experimental data to prove this
