Numerical Simulation on the Texture of Friction Surface Based on Boltzmann Method

  • 摘要: 摩擦表面的表面织构具有改善摩擦副表面接触方式和润滑状态的作用。采用格子Boltzmann方法对表面织构进行数值模拟分析,采用D2Q9二维速度模型,非平衡外推边界处理格式,编写了模拟的计算程序,模拟出二维方槽、三角形槽及梯形槽织构表面的流动。针对上述流动,计算出雷诺数不同时的流线图,并分析了不同形状凹槽流动的变化,计算了不同形状、深度条件下阻力系数的变化并概括了影响规律。通过对表面阻力的比较发现:梯形凹槽是最优的表面织构;由方形槽的模拟可知,织构形状的深径比也存在最优值,从而证明了Boltzmann方法是模拟复杂流体运动的有效方法。
