With the vigorous development of maritime trade, frequency band from 100 to 1500 Hz shallow-sea ambient noise is not only affected by surface wind-induced but also contribution ship noise. Shallow-sea can be described a linear combination sources and sources. By using correspondence between real part vertical coherence energy flux, this work establishes combined source model based on coherence. A 64-element array used measure ocean 103 m deep in an area South China Sea. Two scenarios, one...
Flow past tandem cylinders in non-Newtonian fluids represent a fundamental problem with significant engineering implications. In this study, we employ the multiple-relaxation-time lattice Boltzmann method single-node second-order curved boundary scheme to investigate power-law fluid flow fixed and rotating cylinders. The investigation covers indices from 0.6 1.6 spacing ratios 1.2 8.0, focusing on drag inversion phenomenon, force characteristics, wake interference patterns. Our results...
A shield tunnel is an assembled structure that composed of segments and connecting bolts, its longitudinal seismic response needs to be investigated. Bolt prestress a common measure for tunnels, bolts with different can affect the deformation stiffness tunnels; therefore, they characteristics tunnel. Based on this, this paper establishes analysis model considers bolt uses iterative algorithm study effect force opening tunnels under transverse excitation. Further, detailed circumferential...
This article described relative humidity (RH) sensing using a ZnO-based film bulk acoustic-wave resonator (FBAR). The resonant frequency of the FBAR decreased in two-stage manner as RH increased. For low RH, downshift 2.2 kHz per 1% change was observed. effect attributed to water molecules replacing adsorbed oxygen on ZnO surface, thus increasing density film. high 8.5 obtained, which due mass loading layers formed surface.
The frosting type and degree of the outdoor heat exchanger air source pump (ASHP) in heating season are greatly affected by local environmental temperature humidity. China has a vast territory, climate varies different regions. Therefore, when ASHP is running zones for winter, there significant differences degree. In order to achieve deeper understanding frost formation provide more accurate guidance suitability application antifrosting defrosting technologies, study on division was...
In this work, alumina-graphene (Al 2 O 3 -G) composites with graphene contents ranging from 0.5 to 3% were prepared by stepwise feeding ball milling and hot pressing. The influences of content on the microstructure mechanical properties Al -G investigated. Results showed that densification, grain sizes, flexural strength, fracture toughness Vickers hardness materials increased firstly then decreased increasing contents. When was 1%, value each performance parameter reached maximum. average...
Underwater noise produced by rainfall is an important component of underwater ambient noise. For example, the existence causes strong disturbances to sonar performance. The a single raindrop basis Therefore, it necessary study associated when drops strike water surface. Previous research focused primarily on sound pressure and frequency spectrum from raindrops, but its energy insufficient. purpose this paper propose method for predicting acoustic generated raindrops any diameter. Here,...
In order to perform flow velocity measurements without interfering in the field itself, a measurement method based on characteristics (the rule by which power spectrum varies with velocity) of turbulent pressure fluctuations is proposed. This boundary layer (TBL) and uses polyvinylidene fluoride (PVDF) sensor convert into voltage outputs. First, TBL fluctuation are studied. Second, piezoelectric PVDF sensors studied array signal processing that can improve signal-to-noise ratio provided....
