| 1 | Dust dispersion and management in underground mining faces显示文摘Presence of fine dust in air causes serious health hazard for mine operators resulting in such serious problems as coal workers’pneumoconiosis and silicosis.Major sources of dust appear of course along the mining face where the minerals are extracted.Proper control and management are required to ensure safe working environment in the mine.Here,we utilize the computational fluid dynamic(CFD)approach to evaluate various methods used for mitigating dust dispersion from the mining face and for ensuring safe level of dust concentration in the mine tunnel for safety of the operators.The methods used include:application of blowing and exhaust fans,application of brattice and combination of both.The results suggest that among the examined methods,implementation of appropriately located brattice to direct the flow from the main shaft to the mining face is the most effective method to direct dust particles away from the mining face. | Kurnia Jundika Candra Sasmito Agus Pulung Mujumdar Arun Sadashiv | 2014 | International Journal of Mining Science and Technology2014，24，1： | 39 |

| 8 | Introduction and evaluation of a novel hybrid brattice for improved dust control in underground mining faces: A computational study显示文摘A proper control and management of dust dispersion is essential to ensure safe and productive underground working environment. Brattice installation to direct the flow from main shaft to the mining face was found to be the most effective method to disperse dust particle away from the mining face. However,it limits the movement and disturbs the flexibility of the mining fleets and operators at the tunnel. This study proposes a hybrid brattice system- a combination of a physical brattice together with suitable and flexible directed and located air curtains- to mitigate dust dispersion from the mining face and reduce dust concentration to a safe level for the working operators. A validated three-dimensional computational fluid dynamic model utilizing Eulerian–Lagrangian approach is employed to track the dispersion of dust particle. Several possible hybrid brattice scenarios are evaluated with the objective to improve dust management in underground mine. The results suggest that implementation of hybrid brattice is beneficial for the mining operation: up to three times lower dust concentration is achieved as compared to that of the physical brattice without air curtain. | Kurnia Jundika C.

| 10 | 工业干燥的革新现状与研发需求显示文摘在过去的30年,全球干燥研发活动呈现出快速增长趋势。尽管热力干燥在几乎所有主要工业生产部门都是一个重要的单元操作,干燥基础和工业应用研究却是在上世纪70年代早期发生能源危机后才开始兴起。随后石油价格下跌,但人们已认识到改善干燥操作以节省能源、提高产品质量、减少环境影响的重要性;最近几年更增强了这种意识。新的干燥技术、更好的操作措施和干燥机控制策略、先进和可靠的放大方法,已经帮助生产出低成本和高质量的干燥产品。由于没有一个普遍适用的干燥理论,多数干燥数学模型仅适用于特定的产品和设备。本文将讨论革新在不同工业干燥部门如纸张、木材、农产品、废弃物等所发挥的作用,概述过去30年干燥研究的进展和面对的挑战,指出一些需要继续研究努力的干燥领域,举例讨论通过数学模型强化干燥器设计的革新,同时强调指出,学术界与工业界紧密互动是未来10年干燥研发获得成功的关键。 | Arun S Mujumdar 吴中华 | 2007 | 干燥技术与设备2007，5，2： | 4 |
| 11 | DEM simulation of polydisperse systems of particles in a fluidized bed显示文摘Numerical simulations based on three-dimensional discrete element model (DEM) are conducted for mono-disperse, binary and ternary systems of particles in a fluidized bed. Fluid drag force acting on each particle depending on its size and relative velocity is assigned. The drag coefficient corresponding to Ergun’s correlation is applied to the system of fluidized bed with particle size ratios of 1:1 for the mono-disperse system, 1:1.2, 1:1.4 and 1:2 for the binary system and 1:1.33:2 for the ternary system by keeping total volume and surface area of the particles constant. Results indicated that a reasonable estimation of drag force based on individual particle diameters as compared to that of the mean diameter of the particles is achieved in the fluid cells. The total translational kinetic energy of the particles is found to increase as the particle size ratio increases, suggesting an enhanced momentum transfer in polydisperse particle systems. Systems with wide particle size distribution exhibited higher particle velocities around bubbles, resulting in faster bubble growth and its subsequent rise through the fluidized bed. | Nobuyuki Tagami Ajit Mujumdar Masayuki Horio | 2009 | Particuology2009，7，1： | 3 |
