In common with manufacturers, considerable efforts have been made nearly 40 years to investigate 3D blade stacking arrangement to improve turbine performance. Stacking line modifications are often used in turbomachinery as a means of controlling the degree of reaction, blade loading and secondary flows. Although 3D blade designs has been proved as an effective way of controlling blade loading and secondary flow, its influence on turbine performance and efficiency is not completely understood. The aim of this study is to understand the mechanism and the consequence of the compound lean blade on multistage performance and efficiency on the industrial gas turbine. In order to analysis the effect of compound lean, this paper discusses the CFD results focusing on pressure gradient, blade loading and entropy function.
