Abstract

As is known that dependences of colloidal suspensions properties on concentration of the impurity (nanoparticles) is more complex than in rough suspensions. The viscosity of a colloidal mixture depends not only on the volume fraction of the impurity, but also on the material and size of the particles. In addition, stabilizers are used in most colloids, which prevent the formation of large clusters of aggregated particles. Two nanofluids consisting of the same components can significantly different on property, because they have a differ fractional composition or method of stabilization.  Nanofluids have a many mechanism of transport impurity. To analises this mechanism we mast know phusical property of the fluid. In this study investigation temperature and concentration dependence of viscosity, density and refractive index for suspension water-SiO2 . Measurements made in interval of mass concentration from 0 to 10%, and temperature interval from 20 to 30 °С. Range of temperature and concentration deviations at which constant viscosity approximation is valid, was determined.
