Four new organoantimony carboxylates, (R–COO)2SbR′3 [R–COOH = (±)-2-phenoxypropionic acid and R′ phenyl (1), 4-fluorophenyl (2), 3-fluorophenyl (3), 3,4,5-trifluorophenyl (4)], were synthesized structurally characterized by elemental analysis, 1H, 13C NMR, IR X-ray single crystal diffraction. Structural analyses reveal that 1–3 show similar five-coordinate trigonal bipyramidal geometries, binding with three aryl groups two deprotonated unidentate ligands. Unexpectedly, 4 exhibits pentagonal...
Based on discrete element theory, a model was built to simulate the motion of single particle or particles, which provides some feasible and effective methods for determining physical parameters contact model, improves authenticity reliability material simulation. This paper obtaining mutual parameters. The shear modulus limestone rock obtained by uniaxial compression test. Using raw material, collision recovery coefficient measured in drop test using high-speed camera static friction...
Abstract Manufactured sand often has granules with uneven shapes, which affects the quality of concrete. Hence, detection shape manufactured is important to ensure In this article, an image analysis system used detect particle and flow time aggregate angularity test as a reference study correlation between several characterization parameters method. The result shows that equivalent ellipse axial ratio Ae best index for evaluating uniformity shape. Repeatability tests single-grade graded...
The 6D pose estimation methods are employed to ascertain the 3D position and orientation of objects through image recognition. end-to-end method is designed achieve accurate object poses directly. To further improve performance, we propose a learning-based multiple feature guidance network (MFG-Net) for regression. This simultaneously regresses dense coordinate maps, visible segmentation surface region 2D directional vector maps. By guiding with features, construct 2D-3D correspondences more...
Eddy current sensors are increasingly being used to measure the dynamic blade tip clearance in turbines due their robust anti-interference capabilities and non-contact measurement advantages. However, research primarily focuses on enhancing performance of eddy themselves, with few studies investigating influence turbine rotor parameters measurements taken by these for clearance. Hence, this paper addresses gap using COMSOL Multiphysics 6.2 software establish a finite model circuit...
Given the increasing application of eddy current sensors for measuring turbine tip clearance in aero engines, enhancing performance these is essential improving measurement accuracy. This study investigates influence coil shape on planar and identifies an optimal to enhance sensing capabilities. To achieve this, various shapes-specifically circular, square, rectangular wave, triangular wave-were designed fabricated, featuring different numbers turns experiment at room temperature. By...
This study investigates the effect of impact velocity and particle size on crushing characteristics. We use a discrete‐element method simulation construct cohesive limestone particles with internal microinterfaces cracks for experimentation. The model follows same process as experiment. Results show that, after at velocities 30 40 m/s, simulated particle‐size distribution curve matches experimental results closely 95%. For different sizes, are more than 90% in agreement. These indicate...
Abstract At low Reynolds numbers operating condition, the boundary layer of high-lift low-pressure turbine (LPT) aero-engines is prone to separate on suction surface airfoil. The profile losses airfoil are largely governed by size separation bubble and transition process in layer. However, wake-induced transition, natural instability induced Klebanoff streaks complicate process. a LPT was investigated at Re = 50,000 with upstream wakes. numerical simulation performed CFX software using large...
