Real-Time Heat-Sink Capability Monitoring Framework of Fuel Thermal Management System

Wenjie Zhou, Chao Zhang, Jiang Lei, Hong Lu et autres

With the proliferation of high-power electronics, electric propulsion, and directed-energy weapons, thermal management has evolved from a high-speed flight concern into a systemic bottleneck across subsonic, transonic, and supersonic aircraft. Conventional fuel thermal management systems rely on engine inlet fuel temperature as …

Sampling-simulation-based spatial analysis and strategy optimization for compaction quality assurance

Wang You-le, Zhijun Zhang, Zhengjian Miao, Feng Wang et autres

Compaction quality is crucial for geotechnical performance, but spatial autocorrelation introduces risks of misjudgment. This study presents a simulation-based framework to optimize sampling schemes for quality assurance. First, a practical algorithm is introduced to estimate the scale of fluctuation using the geostatistical …

Concrete cracking risk analysis of a dam based on KABWO-SVM response surface and structural reliability method

Wenjie Zhou, Feng Wang, Youle Wang, Yuhang Li et autres

For the pre-assessment of cracking risk in concrete dams, deterministic analysis is traditionally performed based on temperature control design data. However, numerous uncertainties inherent in the construction process inevitably affect the reliability of temperature and stress field simulations. Accordingly, this study considers …

Rotor–stator interaction and its induced noise suppression in a centrifugal pump with the staggered impeller

Jiarong Gu, Bo Gao, Ning Zhang, Shun Liu et autres

The staggered impeller (SI) is an effective strategy for enhancing flow stability, improving energy efficiency, and suppressing pressure pulsations in double-suction pumps. In the present paper, SI in an end-suction centrifugal pump is proposed. Its effect on the acoustic signature is investigated …

Leakage and Rotordynamic Performance of a Semi-Y Labyrinth Seal Structure for Centrifugal Pump Based on Multifrequency Whirl Method

Wenjie Zhou, Huihao Su, Hui Liu, Yang Zhang et autres

Abstract A semi-Y labyrinth seal (SYLS) is proposed to reduce leakage and enhance the stability of centrifugal pump. The calculation adopts a multifrequency circular whirling model with two-control user-defined functions (UDFs) and the numerical predictions align closely with experimental data for labyrinth …
