Purpose The purpose of this paper is to augment heat transfer rates traditional rib-elements with minimal pressure drop penalties. Design/methodology/approach novel geometries in the present research are conventional cylindrical ribs rounded transitions adjacent flat surfaces and modifications at their bases. All turbulent fluid flow results presented using computation dynamics a validated v2f turbulence closure model. Turbulent characteristics performances square channels improved ribbed...
Deep learning is currently the mainstream approach for building extraction tasks in remote-sensing imagery, capable of automatically features buildings imagery and yielding satisfactory results. However, due to diverse sizes, irregular layouts, complex spatial relationships buildings, extracted often suffer from incompleteness boundary issues. Gaofen-7 (GF-7), as a high-resolution stereo mapping satellite, provides well-rectified images its rear-view which helps mitigate occlusions highly...
Rainstorm disasters have wide-ranging impacts on communities, but traditional information collection methods are often hampered by high labor costs and limited coverage. Social media platforms such as Weibo provide new opportunities for monitoring analyzing disaster-related in real-time. In this paper, we present ETEN_BERT_QA, a novel model extracting event arguments from rainstorm disaster texts. The incorporates the text enhancement network (ETEN) to enhance extraction process improving...
To solve safety problems of construction machine on working in work site, technologies have been developed as the last barrier. Active need to acquire data identify danger, so information technology plays an important role. In this paper, definition is illustrated and some current active examples are shown. The key used analyzed, such Real-time sensor, processing visualization. function fail control system coming from electrical, electronic, programmable systems (E/E/PS), design taken...
As modern turbines are designed with low aspect ratio and high blade loading, secondary flow interactions become more important. In the present work, numerical simulation is performed in a two-stage high-pressure turbine divergent meridional passage to investigate transport interaction of vortex from first stage rotor within second stage’s stator. Scale-Adaptive Simulation model coupled Shear Stress Transport (SAS-SST turbulence model) used capture structures caused by Coupled rotor, shed...
This study discusses the low-impact development (LID) facility planning of Phase 1 project Guangzhou Educational Town in China. The site will deploy LID facilities to reduce flood risk and nonpoint pollution utilize rainwater for landscaping irrigation. In addition traditional facilities, two newly developed features such as gravel infiltration retention system depressive green field are used first time project. low- high-density configurations were deployed. SWMM model was stimulate runoffs...
Aerial work vehicles are widely used in a variety of aerial scenarios. In these vehicles, energy-saving is realized by telescopic motion control. Due to boom and person-mounting, their safety requirements very high. The anti-rollover protection function one important active technologies, which mainly through electrical, electronic, programmable systems. At present, there lack accurate dynamic quantitative evaluation methods for functional level, this problem can be solved method based on the...
Floods are serious threats to the safety of people’s lives and property. This paper systematically introduces basic theories methods flood risk assessment, takes Sichuan Province as study area, establishes a assessment index system with 14 indicators in four aspects—disaster-causing factors, disaster-forming environment, disaster-bearing body, regional disaster resilience capacity—from causes losses formation mechanisms. Furthermore, this constructs model for based on cloud model, entropy...
Hydraulic characteristics of unsteady flows were investigated experimentally when flood waves passing through compound open channels. Some noticeable features flow structure in channels revealed which significantly different from those single rectangular The unsteadiness velocity becomes very large main and the peak appears earlier than Lateral shear stress increases a rising stage at an interface region channel plain. bed exceeds value steady stage.
For the finger seal, leakage and wear are key factors to affect its sealing performance service life. To reduce of C/C composites probably used for seal material preparation self-lubrication light weight properties compared with metal. The work be presented here assessed elastic 2.5D by volume average method established a finite element model dynamic analysis. results show that increasing warp yarn density using shallow direct-joint structure can notably improve but also increase contact...
Abstract A numerical analysis of the effect Mach number on boundary layer development and aerodynamic performance a high-lift, after loaded low pressure turbine blade is presented in this paper.
