Flow characteristics in a rotor-stator cavity with cooling air inlet at low radius
cooling system rotor-stator system flow characteristics pressure distribution resistance coefficient
2015/5/12
Experiments were conducted on a typical rotor-stator system where air entered through an annular slot at low radius and flowed out of the cavity axially through a rim seal between the rotor and the st...
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...

离心泵泵腔内流动特征的数值分析（Numerical Study of Flow Characteristics in the Impeller Side Chamber of Centrifugal Pump）
离心泵 泵腔 密封环间隙
2009/5/22
为了分析离心泵在设计工况运行时叶轮盖板两侧泵腔内流场结构的特点，采用RNG k-ε湍流模型和多重参考系下的雷诺时均N-S方程，对由叶轮通道、蜗室、泵腔和密封环间隙组成的计算域进行定常数值模拟。计算结果与试验结果吻合良好，证明了数值计算方法具有较高的可靠性。流场分析结果表明，泵腔内的流场分布具有非轴对称性，其流场结构比由转子—定子组成的封闭壳体内的流场结构复杂得多，但二者的速度场沿轴向的变化规律相似...
