![]() ![]() For hybrid nanofluids, thermal conductivity is measured to be 1.042 W/mK at 1.0 percent concentration at 80 ☌. Fluids that don’t produce a constant are called Non-Newtonian fluids. Fluids that produce a viscosity constant are known as Newtonian fluids. At 20 ☌, 1.0 percent hybrid nanofluids have a maximum viscosity of 4.009 cP, which is higher than the base liquid viscosity of 3.040 cP. The units of dynamic viscosity are Ns/m 2 (Ns m -2 ), or mPa.s, or the SI unit Poiseuille (where 1 centi-Poiseuille 1 mPa.s for water at 20 o C). Nanofluids' thermal conductivity rose as volume concentration and temperature increased. ![]() Godfrey Published 1952 Physics Journal of research of the National Bureau of Standards View via Publisher doi. The viscosity of nanofluids rises with volume concentration and falls with temperature. Absolute viscosity of water at 20-degrees-C J. The TPS 500S thermal constants hot disc analyzer is used to evaluate thermal conductivity. The viscosity of a liquid measures its resistance to flow, with consequences for hydraulic machinery, locomotion of microorganisms, and flow of blood in vessels. The LVDV-2 Brookfield Viscometer is used to determine viscosity. FESEM, EDS, and XRD are used to determine the particle size distribution, elemental content, and crystal structure of nanoparticles. Nanofluids with concentrations of 0.2, 0.6, and 1.0 percent are synthesized, and measurements are taken at temperatures ranging from 20 to 80 ☌. Thermal conductivity and dynamic viscosity of Cu-SiO 2/23.5 nm hybrid nanofluids produced in a glycerine-water (30:70 by volume) combination base liquid are presented. ![]()
