摘要：
Unsteady blade row interaction effects can have a significant impact on the efficiency of turbine stages. The axial spacing and blade-count ratio between adjacent blade rows can alter the efficiency and noise generation characteristics of the turbine. Airfoil clocking has been introduced to minimize the adverse effects of blade row interaction. In this paper a two-dimensional unsteady viscous now analysis has been used to study the performance variations of a 1-1/2 stage turbine due to clocking of second-stage stator airfoils.
