| 2 | New formula for drag coefficient of cylindrical particles显示文摘The drag force on a cylindrical particle is calculated using lattice Boltzmann method.The results show that the drag coefficient of a particle with different orientation angles decreases with increasing Reynolds number.When the principal axis of the particle is parallel to flow,the drag coefficient is much larger than that of others and decreases fastest with increasing Reynolds number,which becomes more obvious with increasing particle aspect ratio.When the principal axis of the particle is inclined to flow,the drag coefficient is nearly the same for different particle aspect ratios.In the case of flow with small Reynolds number (Re<100),the drag coefficient decreases with increasing orientation angle at different aspect ratios and Reynolds numbers.The drag coefficient is more sensitive to particle orientation angle when the particle orientation angle is small and the aspect ratio is large.Finally,a new correlation formula for the drag coefficient of cylindrical particle is established,with which the drag force on a cylindrical particle can be directly calculated based on the Reynolds number,particle aspect ratio and orientation angle. | Xiaohui Guo Jianzhong Lin Deming Nie | 2011 | Particuology2011，9，2： | 6 |
| 3 | A LB-DF/FD Method for Particle Suspensions显示文摘In this paper, we propose a lattice Boltzmann (LB) method coupled with adirect-forcing fictitious domain (DF/FD) method for the simulation of particle suspensions. This method combines the good features of the LB and the DF/FD methodsby using two unrelated meshes, namely, an Eulerian mesh for the flow domain and aLagrangian mesh for the solid domain, which avoids the re-meshing procedure anddoes not need to calculate the hydrodynamic forces at each time step. The non-slipboundary condition is enforced by introducing a forcing term into the lattice Boltzmann equation, which preserves all remarkable advantages of the LBM in simulatingfluid flows. The present LB-DF/FD method has been validated by comparing its results with analytical results and previous numerical results for a single circular particleand two circular particles settling under gravity. The interaction between particle andwall, the process of drafting-kissing-tumbling (DKT) of two settling particles will bedemonstrated. As a manifestation of the efficiency of the present method, the settlingof a large number (128) of circular particles is simulated in an enclosure. | Deming Nie Jianzhong Lin | 2010 | Communications in Computational Physics2010，7，3： | 3 |
| 4 | A fluctuating lattice-Boltzmann model for direct numerical simulation of particle Brownian motion显示文摘A single-relaxation-time fluctuating lattice-Boltzmann (LB) model for direct numerical simulation (DNS) of particle Brownian motion is established by adding a fluctuating component to the lattice-Boltzmann equations (LBEs). The fluctuating term is proved to be the random stress tensor in fluctuating hydro-dynamics by recovering Navier-Stokes equations from LBEs through a Chapman-Enskog expansion. A three-dimensional implementation of the model is also presented, along with simulations of a single spherical particle and 125 spherical particles at short times. Numerical results including the mean-square displacement, velocity autocorrelation function and self-diffusion coefficient of particles compare favorably with theoretical results and previous numerical results. | Deming Nie | 2009 | Particuology2009，7，6： | 3 |
| 5 | Direct Numerical Simulation of Multiple Particles Sedimentation at an Intermediate Reynolds Number显示文摘In this work the previously developed Lattice Boltzmann-Direct Forcing/Fictitious Domain(LB-DF/FD)method is adopted to simulate the sedimentation of eight circular particles under gravity at an intermediate Reynolds number of about 248.The particle clustering and the resulting Drafting-Kissing-Tumbling(DKT)motion which takes place for the first time are explored.The effects of initial particleparticle gap on the DKT motion are found significant.In addition,the trajectories of particles are presented under different initial particle-particle gaps,which display totally three kinds of falling patterns provided that no DKT motion takes place,i.e.the concave-down shape,the shape of letter“M”and“in-line”shape.Furthermore,the lateral and vertical hydrodynamic forces on the particles are investigated.It has been found that the value of Strouhal number for all particles is the same which is about 0.157 when initial particle-particle gap is relatively large.The wall effects on falling patterns and particle expansions are examined in the final. | Deming Nie Jianzhong Lin Mengjiao Zheng | 2014 | Communications in Computational Physics2014，16，8： | 2 |

| 9 | Pore-fillings of dolomite reservoirs in Sinian Dengying Formation in Sichuan basin显示文摘The Sinian Dengying Formation in the Sichuan basin is an important potential reservoir for oil and gas exploration in the periphery of the Sichuan basin.Its reservoirs were well developed.And many kinds of fillings which lead to the decrease of pores can be seen in reservoir pores and caves.In this paper,the pore fillings of the Dengying Formation reservoir in Sichuan basin are the object of study.The types and characteristics of the fillings are studied in detail by means of rock slices analysis,cathode luminescence,trace elements and inclusion temperature measurement.The study shows that the fillings include dolomite fillings and siliceous quartz fillings and bitumen fillings.Among them,dolomite fillings can be divided into botryoidal dolomite fillings,foliated dolomite fillings,finely-medium crystalline dolomite fillings and coarse crystalline dolomite fillings.50%–80%of the pores are filled by the dolomite fillings with botryoidal structure,and the pores can be partially full filled;0%–20%of pores are filled by foliated dolomite fillings;20–80%of the pores are filled by finely-medium dolomite fillings;20–80%of the pores are filled by coarse crystalline dolomite fillings.1%–5%of secondary pores are often filled by siliceous quartzs,and the pores can be partially full filled.Bitumen fillings often occur after the above-mentioned fillings,and the residual pores are often semi-filled by bitumens,which makes the original pores and throat smaller and reduces the effective porosity and permeability of the reservoir.So,it is a destructive diagenesis.The pore fillings make the secondary porosity in the reservoir significantly lower,which is not conducive to the formation and preservation of the Dengying Formation reservoir. | Chao Chen Xuefei Yang Xingzhi Wang Deming Zeng Mingyou Feng Lin Xie Xiang Li | 2020 | Petroleum2020，6，1： | 1 |

| 15 | Tissue Culture System for Different Hybrid of Indica Rice显示文摘The effect of varieties and media compositions on callus induction from rice anther and subsequent plant regeneration was studied. The results showed that the callus induction was not significantly different in different media, but mostly depended on genotypes; mean frequency of callus induction on F1 hybrid varieties showed that the medium supplemented with 100 mg · L-1 concentration of the proline was useful for callus induction; when the anther derived callus sub-cultured on MS medium supplemented with BAP (0.5 mg · L-1), KT (1.0 mg · L-1), IAA (0.25 mg · L-1) and NAA (0.5 mg · L-1) for plant regeneration, the frequency of regeneration ranged from 0 to 54.17%, and the highest differentiation index reached 30.5 after sub-cultured for three times; the plants were rooted after transferred to 1/2MS medium with NAA (0.5 mg · L-1) and IAA (0.5 mg · L-1). | WANG Li LIN Gang ZHAO Deming WANG Feng CHEN Jiabin | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，2： | 0 |
| 16 | Design of Low-Power Turbo Encoder and Decoder for NB-IoT显示文摘Turbo code is an error correction coding scheme close to the Shannon limit,usually used in wireless data transmission.Based on the parallel Turbo code algorithm,a parallel Turbo code circuit design scheme is proposed.In the encoder,the recursive systematic convolutional encoder is multiplexed.The decoder is divided into branch metric,recursive,maximum likelihood ratio,and external information calculation modules.The decoding algorithm is based on Max-Log-MAP,controlling the component decoder in parallel.And the state metric calculation in the decoding circuit is combined to reduce the overall power consumption effectively,enabling the encoder and decoder to be used in narrowband Internet of things(NB-IoT).Finally,the hardware scheme of the main functional modules of Turbo code encoding and decoding is designed and implemented.The results show that the dynamic power consumption is less than 50 mW.The overall on-chip power consumption is reduced by 40%at the frequency of 125 MHz compared with previous jobs. | Chong ZHANG Yuhang LIN Deming WANG Jianguo HU | 2024 | Chinese Journal of Electronics2024，33，2： | 0 |
| 17 | A Lattice Boltzmann-Direct Forcing/Fictitious Domain Model for Brownian Particles in Fluctuating Fluids显示文摘The previously developed LB-DF/FD method derived from the lattice Boltzmann method and Direct Forcing/Fictitious Domain method is extended to deal with 3D particle’s Brownian motion.In the model the thermal fluctuations are introduced as random forces and torques acting on the Brownian particle.The hydrodynamic interaction is introduced by directly resolving the fluid motions.A sphere fluctuating in a cubic box with the periodic boundary is considered to validate the present model.By examining the velocity autocorrelation function(VCF)and rotational velocity autocorrelation function(RVCF),it has been found that in addition to the two relaxation times,the mass density ratio should be taken into consideration to check the accuracy and effectiveness of the present model.Furthermore,the fluctuation-dissipation theorem and equipartition theorem have been investigated for a single spherical particle.Finally,a Brownian particle trapped in a harmonic potential has been simulated to further demonstrate the ability of the LB-DF/FD model. | Deming Nie Jianzhong Lin | 2011 | Communications in Computational Physics2011，9，4： | 0 |
| 18 | Experimental research on influence mechanism of loading rates on rock pressure stimulated currents显示文摘The study of pressure stimulated current(PSC)changes of rocks is significant to monitor dynamic disasters in mines and rock masses.The existing studies focus on change laws and mechanism of currents generated under the loading of rocks.An electrical and mechanics test system was established in this paper to explore the impacts of loading rates on PSCs.The results indicated that PSC curves of different rocks had different change laws under low/high loading rates.When the loading rate was relatively low,PSC curves firstly changed gently and then increased exponentially.Under high loading rates,PSC curves experienced the rapid increase stage,gentle increase stage and sudden change stage.The compressive strength could greatly affect the peak PSC in case of rock failure.The loading rate was a key factor in average PSC.Under low loading rates,the variations of PSCs conformed to the damage charge model of fracture mechanics,while they did not at the fracture moment.Under high loading rates,the PSCs at low stress didn’t fit the model due to the stress impact effects.The experimental results could provide theoretical basis for the influence of loading rates on PSCs. | Min Li Zhijun Lin Shiliang Shi Deming Wang Yi Lu He Li Qing Ye Xiaonan Zhang | 2023 | International Journal of Mining Science and Technology2023，33，2： | 0 |
| 19 | Analysis on the combination ability and stability of rice restore line Yihui1577显示文摘Yihui1577 was bred after over 10 generations by crossing R16 and Yunnan purple rice.Many new hybrid rice varieties had been bred with Yihui1577,of which Gangyou1577,Ⅱyou1577,Nyou1577 and Yixiang1577 were certified by Sichuan Province Crop Variety Release Committee,Gangyou1577 and Yixiang1577 were certified by National Crop Variety Release Committee.The series varieties bred with Yihui1577 had been used widely with accumulated areas of 1 200 000 hm2.By using Yihui1577 as breeding material,an excellent restore line Yihui 3003 and some other restore lines,such as Yihui1979,Yihui 315 with good rice quality and good combination ability had been bred.Analysis of combination ability and stability about restore line Yihui1577 was made by using agricultural experimentation and statistical approach.The combination ability analysis was made in complete dual crossing method with 4 CMS lines and 6 restorer lines.It showed that the general combination ability effect value of Yihui1577 was 0.226,while Minghui63 was-0.113.So the general combination ability of Yihui1577 was prior to that of Minghui 63.Stability analysis showed that the F value of Gangyou1577 was 1.81378,while Sanyou 63 was 1.40327,both didn't reach significant level.So Gangyou1577 had the same stability as Sanyou63.The same conclusion had got in the stability analysis of the breeds ofⅡyou 1577,Yixiang1577,Nyou 1577 and so on. | BAO Lingfeng LIN Gang ZHAO Deming LI Yunwu HE Bing | 2007 | Journal of Northeast Agricultural University(English Edition)2007，14，4： | 0 |
