摘要

Abstract

This study investigates the effect of injecting nanofluids containing nano-SiO

as drag reducing agents (DRA) at different concentrations on the pressure drop of air-water flow through horizontal pipe. The test fluid used in this study was air-water with nano-SiO

particles at 0.1%-1% mass concentration. The test sections of the experimental set-up were five pipes of the same length of 9 m with ID from 0.0127m-0.03175m (0.5 to 1.25 in). Air-water flow was run in slug flow regime under different volumetric flow rates. The results of drag reduction (

%) indicated that the addition of DRA could be efficient up to some dosage. Drag reduction performed much better for smaller pipe diameters than it did for larger ones. For various nanosilica concentrations

the maximum drag reduction was about 66.8% for 0.75% mass concentration of nanosilica.
