    Calibration of the DEM sliding friction and rolling friction parameters of a cohesionless bulk material

    查看更多>>摘要：The discrete element method(DEM)has become a valuable tool for understanding the mechanical behaviour of granular assemblies,however,the accuracy of the DEM simulations depends on several interaction parameters such as the sliding friction and rolling friction coefficients.Generally,these pa-rameters are estimated using bulk calibration approach(BCA)where the draw down test has been suggested as an effective way to approach these coefficients.This test provides up to four bulk criteria,the angle of repose,shear angle,mass flow rate and the mass loss which are used to narrow down the possible coefficients.However,there is still more research needed around it to fully understand how this methodology works.An experimental and numerical study was carried out using the draw down test to assess the influence of different mass flow rates and particle shapes on DEM parameters for a cohe-sionless bulk material.It is concluded that use of multi-sphere particles and three aperture sizes in the draw down test to calibrate the sliding and rolling friction parameters of a cohesionless bulk material can converge to a small feasible region in which a single combination of the friction coefficients can be selected.The calibrated sliding and rolling friction coefficients were validated using multi-sphere par-ticles,where the maximum deviation was 5.9％from the experimental values.

    CFD investigation of structural effects of internal gas intake on powder conveying performance in fuel supply systems for aerospace engines

    查看更多>>摘要：Optimal design of gas intake in powder fuel supply systems is crucial for performance of aerospace engines.There is little research on the impact of intake structure on powder conveying performance.Three novel internal intakes were proposed,which are spherical,cube-shaped,and dome-shaped.After validation,CFD simulations demonstrate that fluctuation of mass flow rate of powders in the dome-shaped intake is reduced by about 73.3％compared with the annular external one.Variation trends of phase velocities are similar for the spherical and cube-shaped intakes,while those are similar for the annular external and dome-shaped internal intakes.Fluctuation of area of gas zone for the annular external and spherical internal intakes is larger than that for the cube-shaped and dome-shaped internal intakes.Pressure and relative pressure drop in the fluidization chamber have a stable stage,and fluc-tuation of relative pressure drop is small when dome-shaped internal intake is used.

    查看更多>>摘要：The adsorption performances of individual adsorbent such as UiO-66-NH2 and MgAl-layered double hydroxides(MgAl-LDH)toward levofloxacin(LVX)is less satisfactory due to the disappointing uptake capacity and adsorption efficiency.Herein,a 3D flower-like composite adsorbent prepared via iterative hydrothermal synthesis method anchoring UiO-66-NH2 nanoparticles onto the MgAl-LDH surface.Attributed to the synergistic effects of UiO-66-NH2,and MgAl-LDH,the MgAl-LDH@UiO-66-NH2 exhibits an outstanding adsorption performance toward LVX.Typically,the maximum LVX uptake capacity over MgAl-LDH@UiO-66-NH2 reached 268 mg/g,which was higher than that of the individual adsorption materials UiO-66-NH2(41 mg/g),MgAl-LDH(140 mg/g),and some adsorbents reported in previous literature.The rapid adsorption process can reach equilibrium within 20 min,which conformed well to the pseudo-second-order kinetics and the Langmuir isotherm model.Adsorption thermodynamic result also indicated that the adsorption was spontaneous and exothermic,simultaneous coexisting physical and chemical adsorption interactions.Importantly,the MgAl-LDH@UiO-66-NH2 still maintained excel-lent adsorption capacity with a slightly decrease after fifth cycle,exhibiting a remarkable reuse and stable performances.This work provides a highly novel strategy to prepare recyclable composite adsorbent for the LVX capture from aqueous solution.

    Effects of the nozzle structure and fluidized gas composition on the gas-particle two-phase jet characteristic in a powder fuel scramjet

    查看更多>>摘要：The interaction between nozzle design and fluidization gas composition significantly influences the dynamics within a powder fuel scramjet's combustion chamber.To investigate this relationship,an experimental study utilized high-speed shadow imaging technology to explore the macroscopic aspects of powder fuel injection.The investigation examined various convergence angles,nozzle throat lengths,and fluidized gas compositions.Key findings include:During jet development,powder fuel initially concentrates near the axis,with non-convergence angle nozzles exhibiting longer concentrated distri-bution periods than convergence angle conditions.Decreasing nozzle convergence angles lead to increased penetration distance,frontal velocity,and radial diffusion distance during the initial stages of jet development.Additionally,stable jet shapes show larger divergence angles as nozzle convergence angle decreases,with the largest divergence angle observed at α=60°.In the initial 0-7 ms of jet development,the powder fuel jet demonstrates greater penetration distance and frontal velocity under certain conditions.Moreover,penetration distance and frontal velocity increase with throat length from 7 to 20 ms,accompanied by changes in divergence angles.Specifically,at a throat length(l)of 2 mm,the near-field divergence angle measures 46.50°,and the far-field divergence angle is 22.25°.Conversely,at I=8 mm,the near-field divergence angle is 33.49°,and the far-field divergence angle is 23.21°.The fluidization gas composition minimally affects jet penetration distance and frontal velocity during the initial 0-3 ms.However,due to hydrogen's low density,hydrogen/powder fuel jets exhibit shorter distances and velocities compared to nitrogen/powder fuel jets.Hydrogen fluidization also results in larger divergence angles,particularly in the near field.These findings underscore the importance of nozzle design and fluidization gas composition in optimizing scramjet performance and efficiency.

    A review on the scale-up of high-shear wet granulation processes and the impact of process parameters

    查看更多>>摘要：Wet granulation is one of the most important agglomeration processes,and high-shear granulation(HSG)one of the most employed technologies in the pharmaceutical industry.The most critical process parameters of HSG are discussed in this work.The main concern in scaling up the wet granulation process is the differences between scales,which prevent the particles from having the same experience across all scales.The scale-up of wet granulation processes is commonly divided into two categories:engineering and attribute-based methods.An engineering-based scale-up approach is a strategy based on dimensional analysis and an attribute-based supported on the principles of"equifinality",where process variables are adjusted to obtain equivalent granule attributes.This work presents the effect of different HSG process parameters on the scale-up,as well as the use of process analytical tools(PAT)and modelling strategies.The aim is to review applied scale-up approaches in HSG and discuss benefits and limitations.It is proven why the scale-up for oral solid pharmaceutical products is still considered a hot topic and a very chal-lenging task for development and engineering teams.

    Mixing effects of high-speed jets in gas-solid riser and downer reactors

    查看更多>>摘要：For the high-temperature and short-contact time gas-solid reaction process,riser and downer are considered appropriate reactors.To realize an intensive and complete mixing of reactants with catalysts,the feed raw is always introduced in the form of high-speed jets.In this study,in order to investigate the mixing effects of different types of high-speed jets in riser and downer,traceable ozone is injected with the high-speed feed jets to react with catalyst particles.By detecting the decomposition of ozone,the gas-solid mixing and reaction in riser and downer under the influence of both co-current and counter-current injections are analyzed.The relative ozone concentration is used to reflect the location reaction extent and its radial nonuniformity index is proposed to compare the results in riser and downer.It is found that the jet influence zone in downer provides a relatively better environment for the mixing of feed jets with catalysts.In the riser,introduction of counter-current injections could improve the uni-formity of gas-solid mixing in the initial contact region of feed with catalysts.

    查看更多>>摘要：The present study concerns understanding the effect of process parameters on the characteristics and flowability of nanocrystalline CoNiCrAlY powder synthesized by mechanical milling.Mechanical milling has been conducted in a planetary ball mill with tungsten carbide(WC)ball,with ball to powder ratio of 10:1 at 300 rpm speed,using 1％stearic acid and toluene as process control agent(PCA)with time varying from 10 h to 36 h.The synthesized nanocrystalline powder were characterized by Scanning Electron Microscopy,X-ray Diffraction technique,X-ray Photoelectron Spectroscopy,and Differential Scanning Calorimetry.Subsequently,flowability in terms of Hausner ratio was assessed by Tap Density Tester.Average particle size of the powder was found to decrease from 33 μm to 22 μm after 10 h of milling and further increases to 43 μm and 38 μm after 25 and 36 h of milling,respectively,in stearic acid medium.However,in toluene medium particle size continuously decreases from 33 μm to 9.7 μm with increasing milling time.The particle morphology changes from spherical to platelet shape at low milling hours in both of the media.After 25 h of milling,the shape of the particles is nearly spherical for stearic acid and irregular for toluene used as a PCA.Crystallize size was found to decrease with increasing milling time from 147 nm to 7.7 nm and to 6.4 nm in stearic acid and toluene media,respectively.There was presence of γ,γ',β,hcp-Co,Al2O3 and AlOOH phases on the powder particles milled in both the medium.The measured Hausner ratio of the powders was found to vary from 1.18 to 1.32 in stearic acid medium,and was found to increase with increasing milling time.On the other hand,in toluene media flowability decreases(Hausner ratio increases from 1.33 to 1.44)with increasing milling time.

    查看更多>>摘要：Tumor immunotherapy,particularly cancer vaccines,holds promise for combating cancer by harnessing tailored immune responses against malignant cells.However,conventional approaches face challenges in efficiently delivering antigens for optimal immune activation.Emulsion adjuvants,like MF59,enhance cellular uptake but struggle to induce robust CD8+T cell responses.Here,we introduce a novel strategy employing a water-in-oil-in-water(W/O/W)multiple Pickering emulsion(mPE)for antigen delivery.The mPE,utilizing biocompatible,pH-sensitive particles,encapsulates antigens within the inner water phase,ensuring enhanced intracellular processing and dictating the intracellular fate of antigens for improved cross-presentation.In vitro and in vivo studies demonstrated that mPEs induced robust dendritic cells activation and antigen cross-presentation,leading to a significantly enhanced immune response.Notably,calcium phosphate-stabilized mPE(CaP-mPE)illustrated the more robust IFN-γ+T cell responses.In comparison with traditional surfactant-stabilized multiple emulsions,CaP-mPE significantly inhibit tu-mor growth and effectively prolong the survival of tumor-bearing mice.This innovative approach offers a promising avenue for the development of effective cancer vaccines with potent cellular immune responses.

    查看更多>>摘要：Particle entrainment is an inevitable phenomenon in pipeline systems,especially during the develop-ment and extraction phases of oil and gas wells.Accurately predicting the critical velocity for particle transport is a key focus for implementing effective sand control management.This work presents a semi-supervised learning-deep hybrid kernel extreme learning machine(SSL-DHKELM)model for predicting the critical velocity,which integrates multiple machine learning theories including the deep learning approach,which is adept at advanced feature extraction.Meanwhile,the SSL framework enhances the model's capabilities when data availability is limited.An improved slime mould algorithm is also employed to optimize the model's hyperparameters.The proposed model has high accuracy on both the sample dataset and out-of-sample data.When trained with only 10％of the data,the model's error still did not increase significantly.Additionally,this model achieves superior predictive accuracy compared to existing mechanistic models,demonstrating its impressive performance and robustness.
