导向管喷动床中煤和稻秸粒混料的流动特性试验(Flow Characteristics of Straw with Coal in Draft Tube Spouted Bed)
生物质 气化 喷动床
2010/12/29
将导向管喷动床改进为煤粒和稻秸粒混料气化设备,通过导向管喷动床内进行的稻秸粒与煤粒混合物料冷态流动特性试验,给出喷动的流体力学条件。研究了床层压降随表观风速的变化规律,稻秸粒和煤粒混合比例、喷口直径和导向管喷口间距3因素对床层压降与表观风速关系曲线的影响以及对物料循环速率与风量关系曲线的影响。进行了3因素12拟水平的均匀设计试验,采用SPSS软件进行回归分析,分别得到了物料循环速率、单位床高压降及...

基于Pro/E的水轮机尾水管肘管部分的三维造型(3-D Modeling of Hydraulic Turbine Draft Tube Based on Pro/E)
水轮机 尾水管 CFD
2009/9/25
针对水轮机内部流场CFD数值模拟及工程实际制造需要,对弯肘型尾水管的三维造型进行分析与研究,发现常用的造型方法过程繁琐,且不便于修改流道也不易光滑。本文提出一种新的造型方法,不仅克服了常用方法的弊端,而且造型过程简洁直观、生成的型面平顺光滑,修改过程灵活,适应性强,可更精确地实现设计意图。经实例造型与CFD流场模拟验证,提出的方法不仅设计出的尾水管内部水流运动符合设计假定,其流场分布与理论分析相符...
