| 1 | Numerical investigation of particle saltation in the bed-load regime显示文摘This paper numerically investigates particle saltation in a turbulent channel flow having a rough bed consisting of 2–3 layers of densely packed spheres.In this study,we combined three the state-of-the-art technologies,i.e.,the direct numerical simulation of turbulent flow,the combined finite-discrete element modelling of the deformation,movement and collision of the particles,and the immersed boundary method for the fluid-solid interaction.Here we verify our code by comparing the flow and particle statistical features with the published data and then present the hydrodynamic forces acting on a particle together with the particle coordinates and velocities,during a typical saltation.We found strong correlation between the abruptly decreasing particle stream-wise velocity and the increasing vertical velocity at collision,which indicates that the continuous saltation of large grain-size particles is controlled by collision parameters such as particle incident angle,local rough bed packing arrangement,and particle density,etc.This physical process is different from that of particle entrainment in which turbulence coherence structures play an important role.Probability distribution functions of several important saltation parameters and the relationships between them are presented.The results show that the saltating particles hitting the windward side of the bed particles are more likely to bounce off the rough bed than those hitting the leeside.Based on the above findings,saltation mechanisms of large grain-size particles in turbulent channel flow are presented. | JI ChunNing ANTE Munjiza ELDAD Avital XU Dong JOHN Williams | 2014 | Science China(Technological Sciences)2014,57,8: | 10 |
| 2 | 施钾对小麦/ 玉米产量及土壤钾素平衡的影响显示文摘为指导河南小麦/玉米生产中钾肥的合理施用,于2010-2012年在高、中和低三种土壤供钾水平的试验点,研究了施钾量及施钾技术对小麦/玉米轮作产量、钾肥利用效率及土壤钾素平衡的影响。结果表明,在高钾、中钾和低钾土壤上施用钾肥,玉米分别增产4.76%~12.49%、7.56%~16.08%和7.01%~22.61%;小麦分别增产6.87%~13.87%、11.19%~18.57%和18.71%~27.49%。在不同供钾水平土壤上小麦钾肥利用效率均高于玉米,钾肥偏生产力表现为高钾点〉中钾点〉低钾点,高钾点钾肥当季利用率较高,低钾点的农学效率较高;当施钾量为90、135 kg·hm-2时,小麦和玉米均以钾肥分2次施用效果较好;施钾量为45 kg·hm-2时,玉米以底施较好,小麦以追施较好。低钾和中钾点在施钾量大于45 kg·hm-2时,基本就能维持土壤钾素平衡,而高钾点则在施钾量大于90 kg·hm-2时土壤钾素才有盈余。综合来看,高、中和低钾点适宜的钾肥用量分别在45、90、135 kg·hm-2左右,以钾肥分2次施用效果较好。 | 张辉 张立花 黄玉芳 叶优良 崔建宇 Eldad Sokolowski | 2013 | 麦类作物学报2013,33,5: | 8 |
