This paper proposes the development of a novel coagulant for dust suppression in open-cast mines. Specifically, pretreated sodium lignin sulfonate and acrylic acid were first cross-linked, then graft copolymerization intermediate product (the cross-linking product) acrylamide was conducted finally resulting gelatinous substances crushed. During reaction process, N,N’-methylene-bis-acrylamide ammonium persulfate used as agent initiator, respectively. Subsequently, functional groups,...
The aim of this paper was to develop a model that can characterize the actual micropore structures in coal and gain an in‐depth insight into water’s seepage rules pores under different pressure gradients from microscopic perspective. To achieve goal, long‐flame coals were first scanned by X‐ray 3D microscope; then, through representative elementary volume (REV) analysis, optimal side length determined be 60 μ m; subsequently, using Avizo software, coal’s acquired. Considering porosity varies...
In this paper, a nano Voxel X-ray 3D microscope is used to scan the long flame coal samples and reconstruct pore structure by use of microscopic computed tomography.With image segmentation technique, model micro-pore obtained from reconstructed coal.With different planes selected as seepage inlets, numerical simulation low-pressure water conducted.Studies show that pressure gradually decreases along direction reaches maximum at pore-pipes with good connectivity near inlet.Due difference...
Investigating the mechanism of electromagnetic forming (EMF) becomes a hot topic in field metal forming. The high speed up to 200 m/s EMF makes it real challenge capture process. To this end, new method for measuring displacement at based on induction has been developed. Specifically is used measure an expanding ring driven by pulsed magnetic field; one basic processes. simple and practical, combines high-speed response with adequate precision. measurement system consists printed circuit...
The thermal load of electromagnetic forming coil is one the important factors affecting long continuous service life coil. Study loads in during repeated EMF process necessary before its industrialization, and instructive to design. In this paper, several groups discharges experiments with two different coils were carried out. Fluorescence fiber measurement was applied acquire temperature, it proved be a suitable promising method measuring temperature electrical equipment. A finite element...
Tire burst is one of the hot issues in automobile market. Based on tire problem all-steel radial tire, shear strain and energy density at end belt layer are analyzed to extend durability. A multi-objective optimization model was established by finite element analysis, function constraints conditions were set. The scheme determined using differential evolution (DE) method. simulation durability test specimen show that performance has greatly improved after optimization. results combination...
An oil/water separator with inlet component, perforated plates and coalesence internals was designed in this paper. The influence of the on flow field structures component separation were simulated by commercial software FLUENT. results show that can prevent turbulence eliminate back-mixing effectively. And uniformity best,when distance between two 140mm.The inclined had highest efficiency three structures.
