Abstract

The thermal energy transfers over the two confined solid walls with an ultra thin liquid film placed between them were investigated. The study on solid-liquid (S-L) interface have been found in several engineering applications such as lubrications and coatings. In the past there are a number of study that look into thermal energy and momentum transfer, however the influence of ultra thin liquid film thickness on the thermal boundary resistance has yet to be explored. The methane alkane liquid was examined as ultra – thin film with the thickness of 60 Å, 30 Å and 10 Å to study the influence of the thickness of liquid film on the thermal energy transfer. The method applied in the simulation model for this system is Reversible Reference System Propagator Algorithm (r-RESPA). The characteristics of thermal boundary resistance (TBR) at the S-L interfaces are evaluated based on the temperature jump (TJ) and heat flux at the interfaces. It is found that the value of the heat flux is correlated to the temperature jump (TJ) as it increases along the reduction of the liquid film thickness. The thermal boundary resistance (TBR) is found in inverse correlation with the TJ and the heat flux. The obtained result shows that the liquid film thickness influences the heat transfer at the S-L interface.
