Abstract

The problem arises from the application of nanofluid is that the nanoparticles tend to agglomerate and sedimentation which affect the stability of nanofluid. The aim of the study is to investigate the effect of different surfactant agents and homogenize time on the stability of nanoparticle (SAE 15W 40). In this study, the Nano-oil was prepared by dispersing the nanoparticles with an optimal composition of 0.5 vol.% 70 nm graphite, Al2O3 and ZrO2 in conventional engine oil (SAE 15W 40) grade by using ultrasonic homogenizer for 10-30 minutes. In order to determine the stability of the dispersion, Oleic Acid, SDBS Salt and Sodium chloride were utilized as a surfactant agent with an optimal composition of 0.3 vol. %. The stability test was conducted by using UV-spectrophotometer as quantitative test and observation of sedimentation by using the traditional method as a qualitative test. The collected data were analysed by using the Taguchi method to determine the optimum value of nanoparticle stability. The results of Taguchi analysis show that zirconia nanoparticle with SDBS agent is more stable compared with another sample. Unfortunately, Taguchi analysis analysed on the alumina nanoparticle with an oleic acid agent is a less stable sample.
