To address the misplacement of fine particles in underflow caused by structural defects conventional hydrocyclones, a composite column-cone hydrocyclone (C-C hydrocyclone) was proposed, featuring cone-column-cone structure. Computational Fluid Dynamics (CFD) techniques were employed to study diameter ratio and various configurations C-C hydrocyclone, assessing impact on separation performance. Results indicated that increasing column section from 0.5 0.7 reduced cutting size 22.96 %,...
Abstract To reduce the energy consumption and operational costs associated with thermal sludge drying, this study integrated spray technology drying designed a nozzle specifically for drying. Theoretical research numerical simulations were employed to examine impact of structural parameters on field, optimizing nozzle's angle improve efficiency. The results show that as increases, pressure rises velocity turbulence first decrease then increase. When was 120°, droplets gained maximum kinetic...
The distribution of heat absorption and the mechanisms conductive, convective, radiative transfers between cold particle clusters (Tp = 300 K) high-temperature surfaces (Tw 1173 in fluidized beds were investigated through numerical simulations using MFiX-DEM approach. influence cluster characteristics (εc Dc), restitution coefficients (ep ew), properties (dp, ρp, kp, cp) on various was examined. indicate that convection predominantly governed transfer behavior during process mesoscale...
In order to obtain the optimal cladding process parameters for repairing inner wall of cylinder, 316L stainless steel powder was laser clad onto 27SiMn steel, which is base material cylinder. The CCD (Central Combination Design) experiment scheme designed by response surface method. A surrogate model between input variables (laser power, scanning speed, and powder-feeding speed) values (intactness, dilution rate, micro-hardness layer) established. adaptive chaotic differential evolution...
The Eulerian–Lagrangian approach with a discrete phase model (DPM) is used to investigate the motion trajectories of particles at range 1–50 μm in quick-contact cyclone reactor, which cracking reactions and separations catalysts products can occur respectively simultaneously. results show that typical reactor be described as three types: trapping, escaping dust ring. first corresponds successfully separated from gas flow, while other two types lead more coking erosion reactor. Moreover,...
The different thermal energy performance between spouted, fluidized, and fixed beds when using supercritical CO2 as a fluidizing agent was numerically investigated by employing combined approach of Computational Fluid Dynamics (CFD) Coarse-Grained Particle (CGP) methods. model first validated against experimental data available in the literature, confirming that simulated particle velocity temperature agreed well with measurements. numerical results reveal for spouted bed, gas velocity,...
Perforated plates are prevalently used in various integrated energy systems for flow restriction, vibration, and noise reduction. The characteristics of transfer loss perforated have a significant impact on its piping systems. existing design previous studies largely paid little attention to the variation, resulting severe performance issues consumption. In this study, cavitation with pressure ratios single multi-stage were numerically studied. parameters ratio gradient developed effectively...
Nowadays, the classification of strong-aroma types base Baijiu (base SAB) is mainly achieved by human sensory evaluation. However, prolonged tasting brings difficulties for sommeliers in guaranteeing consistency results, and may even cause health problems. Herein, an electronic tongue (E-Tongue) combined with a gas chromatography-mass spectrometry (GC-MS) method was successfully developed to grade high-alcoholic SAB. The E-tongue capable identifying SAB samples into four grades discriminant...
To reduce the metallurgical defects that are prone to occur in preparation of nickel-based self-lubricating coatings, a method process co-optimization for magneto-thermal-assisted laser cladding coatings is proposed this paper. The energy density, preheating temperature, and electromagnetic intensity selected as input factors; prediction models coating dilution rate, porosity microhardness established by CCD test method; interactive effects magnetic-thermal-assisted on response analyzed,...
