Experimental investigation of viscosity and specific heat of silicon dioxide nanofluids

Abstract: Results of an experimental investigation into the viscosity and specific heat of silicon dioxide (SiO 2 ) nanoparticles with various diameters (20, 50 and 100 nm) suspended in a 60:40 (by weight) ethylene glycol and water mixture are presented. Nanofluids with particle volume percentages ranging from 0 to 10% were examined. Viscosity experiments were carried out over wide temperature ranges, from -35 to 50degC, to demonstrate their applicability in cold regions. The nano- particle diameter effect on the rheology of the SiO 2 nanofluid is explored. Non-Newtonian behaviour was observed for the particle volume concentrations of these nanofluids at sub-zero temperatures. A new correlation was developed from experimental data, which related viscosity with particle volume percent and nanofluid temperature. The specific heats of the SiO 2 nanofluids for various particle volume concentrations are presented.

Standard Test Method for Acid Number of Petroleum Products by Potentiometric Titration

Abstract: 1.2 The test method may be used to indicate relative changes that occur in oil during use under oxidizing conditions regardless of the color or other properties of the resulting oil. Although the titration is made under definite equilibrium conditions, the test method is not intended to measure an absolute acidic property that can be used to predict performance of oil under service conditions. No general relationship between bearing corrosion and acid number is known.
