In the operation of hydroelectric generating unit, thrust bearings generate a considerable amount of residual heat due to load-bearing, friction, and other factors. Poor heat dissipation performance of lubricating oil can give rise to the tile burning phenomenon, thus causing massive economic losses. Nanoparticles can not only improve the lubrication characteristics of lubricating oil but also enhance the heat transfer process of lubricating oil. Accordingly, through numerical simulation, this study examined the heat dissipation enhancement effect of lubricating oil in thrust bearings when reinforced by nano-copper oxide particles with different concentrations (0.1wt%, 0.3wt%, 0.5wt%). The results demonstrate that the addition of nano-copper oxide can enhance the heat dissipation efficiency of lubricating oil, and the most favorable heat dissipation effect is achieved when the concentration of nano-copper oxide is 0.5wt%.

在水轮发电机组运行过程中，推力轴承由于承力及摩擦等因素会产生大量余热，润滑油散热效果差会导致烧瓦现象，从而带来巨大经济损失，纳米颗粒不仅能改善润滑油润滑特性还能增强润滑油换热过程。为此，通过数值模拟仿真，研究了不同浓度（0.1wt%、0.3wt%、0.5wt%）的纳米氧化铜颗粒强化推力轴承润滑油的散热效果。结果表明，通过添加纳米氧化铜可强化润滑油的散热效率，且纳米氧化铜浓度为0.5wt%时散热效果最佳。
