...C. De Maesschalck; V. Andreoli; G. Paniagua; T. Gillen; B. Barker The optimization of the turbine rotor tip geometry remains a vital opportunity to create more efficient and durable engines. Balancing the aerodynamic and thermal aspects, while maintaining the mechanical integrity, is key to reshape...

... in the Part I paper. This Part II paper presents the design flexibilities and optimization strategies. Conjugate heat transfer (CHT) analysis was conducted at a range of Reynolds numbers to assess the thermal performance, loss penalty, and the working mechanism behind. The results show that varying the jet...

... of heat transfer performance of two contoured endwall geometries, one aerodynamically optimized (AO) and the other heat transfer optimized (HTO), with a baseline, noncontoured geometry. The endwall geometries were experimentally investigated at Virginia Tech's transient, blow down, transonic linear...

..., a new method utilizing cascaded optimization and neural networks is proposed in order to broaden the capability of the approach. However, for an integrally bladed disk (blisk), it is not possible to separate the blades and test for mistuning identification separately. For this type of bladed...

...Alejandro J. Rivas-Guerra, Assoc. Mem. ASME; Marc P. Mignolet, Fellow ASME This paper focuses on the determination and study of the maximum amplification of the steady state forced response of bladed disks due to mistuning. First, an optimization strategy is proposed in which partially mistuned...
