当硬盘工作时，磁头滑块飞行在高速旋转的磁盘上方，头/盘界面产生了一层只有几个纳米的气膜，该气膜润滑方程为考虑气体稀薄效应的修正Reynolds方程。为了提高磁记录密度，人们正在考虑用离散磁道（Discrete Track Recording，DTR）磁盘取代传统的光滑磁盘。由于这种DTR磁盘表面磁道和沟槽的影响，在数值求解修正Reynolds方程的过程中，就需要足够多的离散网格来分辨出DTR磁盘表...

本文采用信息扩散保存（D-IP）方法算了 Reynolds 数 100 – 10000 的二维方腔流动。D-IP 方法是一种基于扩散运动观点的分子模拟方法，克服了经典 DSMC 方法对于时间步长和网格大小的严格限制。在本文计算中，D-IP 的时间步长和网格大小分别为分子平均碰撞时间和平均自由程的几十倍乃至几百倍，所得到的方腔流线分布和漩涡的精细结构，均与 Navier-Stokes方程数值解相符。
