A form of steel baffles, which is made poles encased in concrete and embedded into the ground, are introduced this article. This type protective installation to be located on previously identified/designed catchment at multiple levels up hillslope fence off large fallen boulders during landslides or rockfalls. These baffles intended serve as added-on protection filter barriers (array baffles) t...

A multiple-mode metal-insulator-metal plasmonic sensor with four coupled bowtie resonators containing two pairs of silver baffles is numerically investigated using the finite element method and verified by temporal mode theory. The proposed structure can function as a refractive index glucose sensors working in visible near-infrared wavelength ranges. Simulation results show that introducing ca...

Abstract Photocatalysis is an advanced oxidation process, which has been gaining attention as a sustainable technology for tackling pollution. Optimum design, fabrication and scaling up of novel photocatalytic reactors are faced with problems such cost numerous experimental trials optimisation. Computational fluid dynamics (CFD), computer simulation technique can ease the process reactors. The ...

As most classical fluidization technologies, Circulating Fluidized Beds (CFB) are widely employed in chemical and physical operations. However, CFB Reactors still have some disadvantages such as the non-uniform solid particles distribution backflow of near wall, which deteriorate system mixing, lead to low conversion/heat mass transfer rate. To improve performance, we propose current work study...

In this study, the multi-phase Eulerian–Eulerian two-fluid method (TFM) coupled with kinetic theory of granular flow (KTGF) was used to investigate hydrodynamics particle flows (Geldart Group B) in a lab-scale bubbling fluidized bed. The goal improve bubble behavior inside bed distribution an injected liquid, by increasing bubbles entering spray jet cavity and, thus, reduce formation wet agglom...

Sloshing has many industry applications, namely in offshore engineering, aerospace, ship building, and manufacturing. simulation is essential to better understand the sloshing pattern consequently improve tank design reduce noise levels, stresses on structure, optimize baffle configurations arrangements. Thus, aim of this study determine effects perforated (porous) imperforate (solid) baffles p...

Clinical studies suggest that the flow of bile in the biliary system may be a contributing factor in the pathogenesis of cholelithiasis, but little is known about its transport mechanism. This paper reports a numerical study of steady flow in human cystic duct models. In order to obtain parametric data on the effects of various anatomical features in the cystic duct, idealised models were const...

Maturation ponds are used in rural and regional areas in Australia to remove the microbial loads of sewage wastewater, however, they have not been studied intensively until present. Using a combination of culture-based methods and quantitative real-time PCR, we assessed microbial removal rates in maturation ponds at four waste stabilization ponds (WSP) with (n = 1) and without (n = 3) baffles i...

In the field of industry, defect detection based on YOLO models is widely used. real detection, method insulative baffles artificial detection. The work efficiency this method, however, low because depends absolutely human eyes. Considering excellent performance YOLOx, an intelligent YOLOx proposed. First, we selected a CIOU loss function instead IOU by analyzing characteristics baffles. additi...
