项目摘要
Particle entrainment into the gas stream from stationary and moving particle beds is important in a number of industrial and physical environments. It has particlular relavance in rotary kilns, aeolian saltation and hydrological applications were there are strong flow rates adjacent to the surface. Specifically, in rotary kilns where the process material normally rotates as a bed with a highly turbulent flow normal to the rotation, dusting can lead to recycle of 30% of the process material. This recycled material not only reduces process efficiency but also leads to a significant energy cost as the materials is cooled then reheated. The objectives of the proposed research are to characterize and model particle entrainment from inclined stationary and moving particle beds in confined turbulent flows and particle distribution adjacent to rough wall in converging and diverging geometries. This research has the potential to significantly improve process efficiency and to reduce overall energy consumption in particle transport processes.
在许多工业和物理环境中,从静止和移动的颗粒床进入气流的颗粒夹带是很重要的。它特别适用于回转窑、风沙跃迁和靠近地表有强流速的水文应用。具体地说,在回转窑中,工艺物料通常作为一个与旋转正常的高度湍流的床旋转,粉尘可以导致30%的工艺物料回收。这种回收材料不仅降低了工艺效率,而且由于材料冷却然后再加热,还导致了显著的能源成本。所提出的研究目标是表征和模拟受限湍流中倾斜的固定和移动颗粒床的颗粒夹带以及在收敛和发散几何中靠近粗糙壁面的颗粒分布。该研究具有显著提高工艺效率和降低粒子输运过程总体能耗的潜力。
