The present study evaluates the combined use of micro-textures and ‘wettability gradient’ on the thermohydrodynamic performance of inclined slider bearings. Mass conserving Elrod cavitation model with slip boundary condition has been used to investigate the dimensionless static performance parameters at different convergence ratios and sliding speeds. The most effective location of the wettability gradient and textures has been considered in the present work. It has been observed that with the increase in sliding speed, the load carrying capacity, friction force and volumetric inflow rate of the slip-textured bearings were improved. The improvements were more pronounced at smaller convergence ratios. Moreover, the slip-textured bearings exhibited significant improvement in the average pressure and temperature of the lubricant. However, at higher sliding speeds, a substantial increase in friction force and average lubricant temperature was noticed. The square textured slip bearing exhibited maximum improvements towards various performance parameters of the three considered texture shapes.

滑动速度对部分滑移纹理滑动轴承热流体动力性能的影响

本研究评估了微纹理和“润湿性梯度”的结合使用对倾斜滑动轴承热流体动力学性能的影响。具有滑移边界条件的质量守恒埃尔罗德空化模型已用于研究不同收敛比和滑动速度下的无量纲静态性能参数。目前的工作已经考虑了润湿性梯度和纹理的最有效位置。据观察，随着滑动速度的增加，滑动纹理轴承的承载能力、摩擦力和体积流入率均得到改善。收敛比较小时，改进更为明显。此外，滑动纹理轴承在润滑剂的平均压力和温度方面表现出显着改善。然而，在较高的滑动速度下，摩擦力和平均润滑剂温度显着增加。方形纹理滑动轴承对所考虑的三种纹理形状的各种性能参数表现出最大的改进。
