description: Changing the fluids themodynamic properties can sufficiently improve the efficiency of heat transfer equipment. One of the ways to achieve this is to add nanoparticles to a base fluid. The suspensions of fluids with different nanoparicles are being intensivly studied and assumed as innovative technic for heat transfer enhancement in many industrial applications. In this study Al2O3, TiO2 and CuO nanoparticles added to water were considered. The CFD study of nanofluids convection by using a single phase and multiphase model approaches was performed by Ansys Fluent software. The concentration of nanoparticles varied from 1 to 4%. The Reynolds number was equal to 1050, and the pipe geometry was assumed to be the same for all computations. The verification of results obtained for Al2O3 shows a good agreement with the data published by the other authors. The present work contains detailed analysis of temperature and velocity profiles at differenet cross-sections along the pipe. A special attention is paid to heat transfer characteristics and pressure losses computed for pure water flow and different nanofluids. A significant enhancement of heat transfer was observed for all nanofluids, but the highest value corresponded to 4% CuO nanofluid.
