TL;DR: In this paper, the effect of nanoparticles concentration and size on the surface tension of a colloidal mixture of nano-sized particles dispersed in a fluid medium with amended thermo-physical properties was investigated.

TL;DR: In this paper, three types of nanoparticles, namely Al2O3, SiO2 and TiO2, were suspended in methanol solution at five volume fractions (0.005, 0.1%, 0.5, 10, 15 and 20°C) using a KD2 pro thermal conductivity meter.

TL;DR: In this article, the surface tension of the nanofluids was determined by using the Du-Hotly ring method in DCAT11EC automatic surface tensiometer, and the authors analyzed all the possible effects on surface tension with the change in concentrations (from 0.05 to 0.25 vol.) and temperatures (from 30 degrees C to 50 degrees C), as well as the impact of various nanoparticles along with their sizes.

TL;DR: In this paper, different volume concentrations of cylindrical shaped Al 2 O 3 nanoparticles (50mm length and 8mm diameter) were used to produce methanol based nanofluid (MBNF), and the results showed that thermal conductivity, viscosity and density increased while specific heat decreased with increase in particle concentration.

TL;DR: In this paper, the rheological behavior (as shear stress and viscosity with respect to shear rate) of Al2O3-methanol and TiO2-mETHanol were investigated at different volume fractions and temperatures.
