Research Initiation: Surface Roughness and Slip Flow Effects on Ultra-Thin Finite-Width Gas Bearings

利用全雷诺方程的二阶有限差分解，对磁信息存储系统中存在于飞头和硬盘之间的超薄空气轴承的性能进行了数值模拟。横向流动和表面粗糙度方向和形状的影响将包括在模型中，目的是确定哪种表面粗糙度方案将允许最低的飞行高度，从而最大的能量存储密度。

The performance of the ultra-thin air bearings which exist between the flying head and the hard disk in magnetic information storage systems will be modeled numerically by second-order finite-difference solutions of the full Reynolds equation. Effects of cross flow and of surface roughness orientation and shape will be included in the model with the aim of determining which surface roughness scheme will permit the lowest flying height, and thus the greatest energy storage density.
