| 1 | Dynamic Simulation of Shear-induced Particle Migration in a Two-dimensional Circular Couette Device显示文摘The shear-induced migration of neutrally-buoyant non-colloidal circular particles in a two-dimensional circular Couette flow is investigated numerically with a distributed Lagrange multiplier based fictitious domain method.The effects of inertia and volume fraction on the particle migration are examined.The results indicate that inertia has a negative effect on the particle migration.In consistence with the experimental observations,the rapid migration of particles near the inner cylinder at the early stage is observed in the simulation,which is believed to be related to the chain-like clustering of particles.The migration of circular particles in a plane Poiseuille flow is also examined in order to further confirm the effect of such clustering on the particle migration at early stage.There is tendency for the particles in the vicinity of outer cylinder in the Couette device to pack into concentric rings at late stage in case of high particle concentration. | 余钊圣 邵雪明 Roger Tanner | 2007 | Chinese Journal of Chemical Engineering2007，15，3： | 2 |

| 4 | Stress boundary layers in the viscoelastic flow past a cylinder in a channel:limiting solutions显示文摘The flow past a cylinder in a channel with the aspect ratio of 2: 1 for the upper convected Maxwell (UCM) fluid and the Oldroyd-B fluid with the viscosity ratio of 0.59is studied by using the Galerkin/Least-square finite element method and a p-adaptive refinement algorithm. A posteriori error estimation indicates that the stress-gradient error dominates the total error. As the Deborah number, De, approaches 0.8 for the UCM fluid and 0.9 for the Oldroyd-B fluid, strong stress boundary layers near the rear stagnation point are forming, which are characterized by jumps of the stress-profiles on the cylinder wall and plane of symmetry, huge stress gradients and rapid decay of the gradients across narrow thicknesses. The origin of the huge stress-gradients can be traced to the purely elongational flow behind the rear stagnation point, where the position at which the elongation rate is of 1/2De approaches the rear stagnation point as the Deborah number approaches the critical values. These observations imply that the cylinder problem for the UCM and Oldroyd-B fluids may have physical limiting Deborah numbers of 0.8 and 0.9, respectively. | Yurun Fan Huayong Yang Roger I.

| 7 | 制胜文化显示文摘尽管有非常多的企业家们意识到文化的重要性,但贝恩公司最近的一项研究却显示,只有不到10%的企业成功地建立起它们的制胜文化。而且,即使对于那些已经建立起高绩效文化的公司而言,要维持下去也绝非易事。那么,有什么好方法吗? | 狄保莱 Paul Rogers Paul Meehan Scott Tanner | 2007 | 中国企业家2007，，7： | 0 |
