Abstract

The aim of this work is related to an analysis of journal bearings lubrication using non-Newtonian fluids which are described by a power-law model. The performance characteristics of the journal bearings are determined for various values of the non-Newtonian power-law index “” which is equal to: 0.9, 1, and 1.1. Obtained numerical results show that for the dilatant fluids (), the load-carrying capacity, the pressure, the temperature, and the frictional force increased while for the pseudo-plastic fluids () they decreased. The influence of the thermal effects on these characteristics is important at higher values of the flow behavior index “.” Obtained results are compared to those obtained by others. Good agreement is observed between the different results.
使用非牛顿流体的滑动轴承润滑方面分析
这项工作的目的是与使用幂律模型描述的非牛顿流体的滑动轴承润滑分析有关。滑动轴承的性能特征是由非牛顿幂律指数“”的各种值确定的,该指数等于:0.9,1和1.1。得到的数值结果表明,膨胀流体()的承载能力、压力、温度和摩擦力增大,而拟塑性流体()的承载能力、压力、温度和摩擦力减小。当流动性能指数较高时,热效应对这些特性的影响是重要的。将得到的结果与其他人得到的结果进行比较。在不同的结果之间观察到很好的一致性。
