<div>This study aims to predict the impact of porosities on variability elongation in casting Al-10Si-0.3Mg alloy using machine learning methods. Based dataset provided by finite element method (FEM) modeling, two algorithms including artificial neural network (ANN) and 3D convolutional (3D CNN) were trained compared determine optimal model. The results showed that mean squared error (MSE) determination coefficient (R<sup>2</sup>) CNN validation set 0.01258/0.80, while...
Brake wear is an important but unregulated vehicle-related source of atmospheric particulate matter (PM). The single-particle spectral fingerprints brake particles (BWPs) provide essential information for understanding their formation mechanism and contributions. Herein, we obtained the mass spectra BWPs by combining a dynamometer with online single particle aerosol spectrometer quantified real-world BWP emissions through tunnel observation in Tianjin, China. pure mainly include three...
The aerodynamic performance and flow field structure of an inward-turning inlet at a high flying Mach number are attracting more attention. main purpose this paper is to study the back pressure characteristics circular entrance three-dimensional Ma=5.0–8.0, with combination wind tunnel test numerical simulation. This series experiments divided into three parts explore unstart boundary, self-start ability, suction slots influence. experimental results show that design point Ma=6.0, outlet...
The traditional two-way (2W) parabolic equation (PE) (2W-PE) method has been applied for modeling groundwave propagation over irregular terrain. However, based on a staircase terrain model (STM), the is not sufficient in sloping facets modeling. Although more accurate one-way PE conformal mapping (CMM) available, it handles only forward-propagating waves and neglects backward-propagating waves, which become significant especially steep In this paper, hybrid 2W-PE presented to low-frequency...
Abstract TiC particle reinforced Fe 3 Al composites were produced with varying volume fraction of powders. The effect the fractions and distribution on properties was investigated. composite containing 30 vol.% had hardness bending strength values 86 HRA 1340 MPa, which 10% 57% greater than those unreinforced Al, respectively. Microscopic examination showed particles grain size ranging from 50 to 100 nm homogeneously dispersed in matrix, larger sub-micrometer mainly located at boundaries...
Considering the lack of numbers and updates particulate matter (PM) source profiles, which show PM emitted from Chinese iron steel industry, a dilution tunnel system was used to sample discharged three main processes (sintering, puddling, steelmaking) an company in Wuhan, China. Six profiles for fine coarse were established, their characteristics researched. The conclusions as follows:① For sintering SO42-, Al, NH4+ dominant components, with mass fractions 22.2%, 4.5%, 3.5% PM2.5 profile...
