...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...

... consideration is an integrally bladed disk (blisk). This paper presents two new methods to identify mistuning of a bladed disk from the assembly modes via utilizing cascaded optimization and neural networks. It is assumed that a tuned mathematical model of the blisk under consideration is readily available...

...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...
