• J055042 Experimental and Numerical Studies on Secondary Flow Loss in High-Lift Low-Pressure Turbine Airfoils

抄録

This paper details experimental and numerical studies on the secondary flow losses generated in highly loaded LPT (Low - Pressure Turbine) cascades. Secondary flow loss in LPT significantly contributes to its overall loss, especially in increased stage loading and high-lift airfoil cases. Hence it becomes more important to understand the secondary flow loss production mechanisms. The purpose of this study is to clarify the detail of secondary flow losses generated in LPT cascade and to investigate effects of highly loaded LPT airfoils on the secondary flow loss using LPT cascade whose solidity is changeable. Detailed experiments using a 5-hole probe are carried out around endwall regions. In addition, a commercial software, ANSYS CFX, is intensively used for the simulation of the flow fields to enhance the understanding of loss mechanism.
