| 2 | Experimental investigation of particle velocity distributions in windblown sand movement显示文摘With the PDPA(Phase Doppler Particle Analyzer) measurement technology,the probability distributions of particle impact and lift-off velocities on bed surface and the particle velocity distributions at different heights are detected in a wind tunnel. The results show that the probability distribution of impact and lift-off velocities of sand grains can be expressed by a log-normal function,and that of impact and lift-off angles complies with an exponential function. The mean impact angle is between 28° and 39°,and the mean lift-off angle ranges from 30° to 44°. The mean lift-off velocity is 0.81-0.9 times the mean impact velocity. The proportion of backward-impacting particles is 0.05-0.11,and that of backward-entrained particles ranges from 0.04 to 0.13. The probability distribution of particle horizontal velocity at 4 mm height is positive skew,the horizontal velocity of particles at 20 mm height varies widely,and the variation of the particle horizontal velocity at 80 mm height is less than that at 20 mm height. The probability distribution of particle vertical velocity at different heights can be described as a normal function. | KANG LiQiang GUO LieJin LIU DaYou | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，8： | 4 |
| 3 | CFD-DEM simulation of three-dimensional aeolian sand movement显示文摘A three-dimensional CFD-DEM model is proposed to investigate the aeolian sand movement.The results show that the mean particle horizontal velocity can be expressed by a power function of heights.The probability distribution of the impact and lift-off velocities of particles can be described by a log-normal function,and that of the impact and lift-off angles can be expressed by an exponential function.The probability distribution of particle horizontal velocity at different heights can be described as a lognormal function,while the probability distribution of longitudinal and vertical velocity can be described as a normal function.The comparison with previous two-dimensional calculations shows that the variations of mean particle horizontal velocity along the heights in two-dimensional and three-dimensional models are similar.However,the mean particle density of the two-dimensional model is larger than that in reality,which will result in the overestimation of sand transportation rate in the two-dimensional calculation.The study also shows that the predicted probability distributions of particle velocities are in good agreement with the experimental results. | YANG JieCheng,ZHANG Yu *,LIU DaYou & WEI XiaoLin Key Laboratory of Environmental Mechanics,Institute of Mechanics,Chinese Academy of Sciences,Beijing 100190,China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，7： | 3 |
| 4 | Sand storms:CFD analysis of Reynolds stress and collision stress of particles near sand bed显示文摘Sand storm is a serious environmental threat to humans.Sand particles are transported by saltation and suspension,causing soil erosion in one place and deposition in another.In order to prevent and predict sand storms,the causes and the manners of particle motions must be studied in detail.In this paper a standard k-ε model is used for the gas phase simulation and the discrete element method(DEM) is used to predict the movements of particles using an in-house procedure.The data are summarized in an Eulerian-Eulerian regime after simulation to get the statistical particle Reynolds stress and particle collision stress.The results show that for the current case the Reynolds stress and the air shear stress predominate in the region 20-250 mm above the initial sand bed surface.However,in the region below 3 mm,the collision stress must be taken into account in predicting particle movement. | Yu Zhang Jiecheng Yang Dayou Liu Xiaolin Wei Lixin Yu | 2010 | Particuology2010，8，4： | 2 |
| 5 | Dynamics of fine particles in liquid-solid fluidized beds显示文摘On the basis of the Local Equilibrium Model (LEM), fine particles with large Richardson-Zaki exponent n show, under certain conditions during bed expansion and collapse, different dynamic behavior from particles with small n. For an expansion process there may be a concentration discontinuity propagating upward from the distributor, and, on the contrary, for a collapse process there may be a progressively broadening and upward-propagating continuous transition zone instead of discontinuity. The predictions of the bed height variation and the discontinuity trace have been validated experimentally. | Dayou Liu Yuanfang Fu | 2007 | China Particuology2007，5，6： | 2 |

| 8 | Iron-Catalyzed Primary C-H Amination of Sulfamate Esters and Its Application in Synthesis of Azetidinest显示文摘of main observation and conclusion The direct amination of unactivated primary C-H bonds is extremely challenging due to their inert nature.Herein,we report an intramolecular primary C-H amination of sulfamate esters using an iron catalyst derived from iron(Ⅱ)triflate and bipyridine.An array of oxathiazinanes were synthesized in moderate to good yields,which were further converted into biologically important azetidines by a one-pot procedure.This research demonstrates the potential of applying simple nitrogen ligands in iron-catalyzed C-H functionalization and offers an accessible alternative to state-of-the-art iron-nitrene chemistry. | Yan Zhang Dayou Zhong Muhammad Usman Peng Xue Wen-Bo Liu | 2020 | Chinese Journal of Chemistry2020，38，12： | 1 |
