Hydroacoustic reduction mechanism for the bionic hydrofoil

Linfeng Chen, Xianglu Jia, Peng Xu, Dongyang CHEN et autres

A bionic hydrofoil with the features of trailing-edge serrations, leading-edge wavy protuberances, and wavy surface was proposed for the radiation noise reduction. Large eddy simulations were conducted for the near-field unsteady turbulent flows at Reynolds number (Re) 1.0×105 and zero angle of …

Wall-Modeled Large Eddy Simulation of Turbulent Boundary Layer Flows over an Axisymmetric Body of Revolution

Kangjian He, Fuchang Zhou, Jianliang Zhang, Decheng Wan

[Pay attention to the application value of artificial intelligence in the diagnosis, treatment and analysis of sepsis].

Fang Zhou Xu, Wenjie Qin, Fuchang Zhou

In critical care medicine, sepsis management represents a critical barrier to improving clinical outcomes, primarily due to the disease's profound heterogeneity and the current inability to optimally identify patient subgroups benefiting from personalized therapies. Recent advances in Artificial Intelligence (AI) offer promising …

Application of slice spectral correlation density to gear defect detection

Gajula Rukshana Bi, Junjie Chen, Fuchang Zhou, Jun He

The most direct reflection of gear defect is the change in the amplitude and phase modulations of vibration. The slice spectral correlation density (SSCD) method presented in this paper can be used to extract modulation information from the gear vibration signal; amplitude …

Frequency-Demodulated Analysis Based on Cyclostationarity for Local Fault Detection in Gears

Jun He, Jin Chen, Guo Bi, Fuchang Zhou

The demodulation analysis has been extensively used for gear diagnosis. However these techniques mainly deal with the amplitude-modulated signal instead of the frequency-modulated signal. Due to the symmetrical phase relationship of the sidebands, the amplitude-demodulated methods are not suitable for the frequency-modulated …

Application of Degree of Cyclostationarity in Rolling Element Bearing Diagnosis

Guo Bi, Jin Chen, Jun He, Fuchang Zhou et autres

Minor and random slip between rolling elements and races in rolling element bearings makes vibration signals have periodically time-varying ensemble statistics, which is known as cyclostationarity. Two second-order cyclostationary methods, the spectral correlation density (SCD) and the degree of cyclostationarity (DCS), are …
