摘要：
Turbulent flow of fluid samples (polymeric solution, nanofluid and Poly-nanofluid (PNF)), into a horizontal pipeline was investigated to achieve heat transfer properties and drag reduction. Water, Polyisobutylene (PIB) and nanoSiO2 were the materials used in this study. PNFs prepared by dispersing SiO2 nanoparticles (with concentration range of 0.1-1 wt.%) into dilute Water/PIB solution (with concentration range of 10-50 ppm). The effect of polymer and nanoSiO2 presence on heat transfer properties such as convective heat transfer coefficient and Nusselt number were evaluated and Reynolds number changes were studied in this research. At the same time the effect of concentration and Reynolds number on the Nusselt number and drag reduction evaluated by utilizing a statistical method called analysis of variance (ANOVA).(c) 2022 Institution of Chemical Engineers.
