Drag reduction of alumina nanofluid in spiral pipe with turbulent flow conditions

This study was conducted to investigate the effects of nanofluid flows through the spiral pipe on drag reduction in turbulent flow conditions. Al2O3 nanoparticles dispersed into pure water at ratio of 100 ppm, 200 ppm and 300 ppm as well as the duration of the mixing time 30 minutes, 60 minutes and...

Description
Summary:This study was conducted to investigate the effects of nanofluid flows through the spiral pipe on drag reduction in turbulent flow conditions. Al2O3 nanoparticles dispersed into pure water at ratio of 100 ppm, 200 ppm and 300 ppm as well as the duration of the mixing time 30 minutes, 60 minutes and 120 minutes. A circular pipe used as a comparison to spiral pipe and both are mounted horizontally. Spiral pipe ratio is P/Di 10.8 and the inner diameter of circular pipe is 3 mm. Mixing time and composition ratio of nanoparticle in basic fluid influence drag reduction results. Nanofluid flows through the test pipe with Reynolds number between 4.0 × 103 to 2.0 × 104 showed high drag reduction occurred in the spiral pipe is 38%.
