Abstract

Nanolubricant is a type of nano fluid that contains base-fluid lubricant (water or oil) and nanoparticles. This study aims to analyze the thermophysical and rheological properties of lubricants with the addition of nanoparticles. The nanoparticles used are Calcium Carbonate (CaCO3) made from scallop shell waste. The base lubricant is SAE 5W-30 synthetic oil which has quite good performance. Synthesis of Calcium Carbonate (CaCO3) into SAE 5W-30 lubricant uses a two-step method. Variations in the addition of volume fraction of Calcium Carbonate (CaCO3) of 0.05%, 0.10%, 0.15%. Furthermore, the nanolubricant was tested for its thermophysical properties which included thermal conductivity, specific heat, density, viscosity, and sedimentation. After that, the rheology of the nanolubricant can be known from the viscosity data by calculating the shear rate and shear stress.

Abstract

This research uses SAE 5W-30 lubricant base material with the addition of Hexagonal Boron Nitride (hBN) nanoparticle additives. This study aims to analyze the thermophysical and rheological properties of lubricants with the addition of nanoparticles. The method in this study uses a two-step method where nanoparticles are first prepared separately, then added with nanoparticles with varying volume fractions of 0.05%, 0.10%, 0.15% into the base fluid as a processing step. The next step is the stirring process using a magnetic stirrer, and ultrasonic homogenizer process.  Furthermore, the nanolubricant was tested for thermophysical properties including viscosity, density, thermal conductivity, and sedimentation.
