... simple iterations with the succeeding design phases due to method and tool commonalities. While the primary focus of this work is on compressor design, the principles presented are adaptable and expandable to turbine disk applications as well. Turbo Expo, June 24–28, 2024. GT2024. e...

...Valerie Hernley; Jeongseek Kang; Matthew Montgomery; Jae Hoon Chung; Aleksandar Jemcov; Scott C. Morris Nonsynchronous vibration (NSV) in axial compressors can be caused either by (1) unsteady aerodynamic forces that are not related to motion of the blades or (2) motion-dependent aerodynamic...

...Zhaoyin Li; Zeyuan Yang; Pengfei Chai; Zonghan Sun; Jie Tian; Hua Ouyang In this paper, ℓ 1/2 -norm method is used to replace the traditional ℓ 1 -norm to improve the compressed sensing technique. Numerical experiments and fan/compressor tests were performed to validate the applicability...

...Shreyas Hegde; Jonathan D. Inge; Robert Kielb This paper is a continuation of previous papers by the authors that focuses on predicting the mistuned embedded rotor blade forced response. The compressor under consideration is a part of a 3.5stage rig located at Purdue University. Previously...

... compressor is affected by both manufacturing and in-service uncertainty, while the performance of the HP compressor is mainly affected by the manufacturing uncertainty due to its small size. On the one hand, as for manufacturing uncertainty, blade leading-edge shape change, tip/seal clearance increase...

...Klaus Brun; Sarah Simons; Kelsi Katcher; Ryan Cater; Brandon Ridens; Rainer Kurz Gas property prediction is necessary for proper design of compressors. Equations of state are utilized to predict the thermo-physical gas properties needed for such calculations. These are semi-empirical models...

... for lubrication and for heat removal. In order to retain the oil in a bearing chamber, pressurized seals are used. These are pressurized using air from the compressor. In order to avoid overpressurization of the bearing chamber, air/oil passages are provided in the bearing chamber. At the top, a vent pipe...

...Hanlin Sheng; Wei Huang; Tianhong Zhang; Xianghua Huang A schematic of the compression system is presented in Fig. 1 , which includes a compressor, a plenum, a throttle, a bleed valve, and ducts. Due to the constant ambient pressure at the compressor inlet, throttle, and bleed valve's discharge...

... loss factor in subsonic and transonic axial flow compressors depends strongly on approximate correlations for calculating the blade wake momentum thickness, and therefore represents such a case. This study demonstrates this by looking into an iterative approach to blade profile loss model adaptation...
