Surface wettability pattern and shape gradient co-induced oil droplet directional transport for enhancement of lubrication performance
Thermocapillary migration in lubrication systems is a phenomenon in which the lubricant migrates via the interfacial tension difference caused by the nonuniform temperature generated by the wear behavior, which leads to lubricant starvation and results in severe damage.This paper proposes a novel method to eliminate the thermocapillary migration ph
