Effect of Temperature and Nanoparticle Concentration on the Viscosity of Glycerine-water based SiO2 Nanofluids

Dynamic viscosity of SiO2/22nm nanofluids prepared in a glycerine-water (30:70 by volume) mixture base liquid, referred to as GW70, is measured experimentally. Nanofluids with concentrations 0.2, 0.6, and 1.0 percent are produced, measurements carried out at temperatures ranging from 20 80 oC using LVDV-2T model Brookfield Viscometer. The particle size elemental composition nanoparticles determined FESEM EDX. XRD images confirm the SiO2 peaks crystalline structure. rheology influenced nanoparticle’s concentration. In experimental temperature concentration range, show Newtonian behavior. enhanced increased reduced increased. For vol. 20oC, maximum value achieved, for 0.2 80oC, lowest observed. fluid was also 20, 40, 60, degrees Celsius. ratio liquid found be more than one all nanofluids. This data useful estimate HTC glycerine-water-based silica
