摘要

根据全尺寸(14英寸)磁盘驱动器的几何形状和Ekman数，对刚性磁盘驱动器的流体力学进行了实验模拟。研究了三种不同的流动结构。第一个是用于确定流的基本结构的简化几何。第二个案例探讨了将冷却流引入基本几何结构的影响，第三个案例考虑了由于读取头支撑的存在而导致的堵塞的单独影响。这三种情况都表现出靠近旋转轮毂的流动形式，与远离轮毂的流动形式不同。此外，每个流配置都包含其他情况中没有的特性。讨论了这些流特征对磁盘驱动器性能的影响

Flow visualization and spectral measurements in a simulated rigid disk drive

An experimental simulation of the fluid mechanics of a rigid disk drive has been performed matching the geometry and Ekman number of a full-size (14 in.) disk drive. Three different flow configurations have been studied. The first was a simplified geometry used to determine the basic structure of the flow. The second case explored the effect of the introduction of cooling flow into the basic geometry, and the third considered the separate effect of the blockage due to the presence of the supports for the read heads. All three cases exhibited flow regimes near the rotating hub which were distinct from the flow farther from the hub. In addition, each of the flow configurations contained features not found in the other cases. The implications of these flow features with respect to disk drive performance are discussed.<>
