Abstract

Solid-liquid (S-L) interfaces is widely used in lubrication and coating systems, in which the heat transport is the main problem for the system. In the recent years, lubrication and coating systems have been investigated up to the molecular scale to solve the problem of heat transport due to wear and friction. In molecular scale, the characteristics of heat transport are different from the conventional one. Therefore, the purpose of this study is to specifically investigate the characteristics of heat transport in the molecular scale at the S-L interfaces. The prime concern in this numerical investigation is the surface structure of solid and the type of liquid molecules. The characteristics of heat transport at the S-L interfaces are evaluated based on the temperature jump (TJ) and thermal boundary resistance (TBR) at the interfaces. It is found that the different TJs and TBRs can be observed for variation of the surface structures and the length of liquid molecules. The obtained results show that the surface structures and length of liquid molecules significantly affect the characteristics of heat transport at S-L interfaces.
