... loaded blades are to be utilized. The present study analyzes the secondary flow field of the front-loaded low-pressure turbine blade designated L2F with and without blade profile contouring at the junction of the blade and endwall. The current work explores the loss production mechanisms inside the LPT...

... compared to roughness loss increases reported in the literature. For example, Boyle and Senyitko [ 18 ] show an increase of loss up to 50% in the transonic regime for values of Ra /c one order of magnitude lower than the present data. This may be because their turbine blades never experienced separation...
