Laminar heat transfer with alumina nanofluid in cu tube with different diameters

This study made nano particles-dispersing alumina nano fluid to three sized copper tubes in order to identify the differences in its heat transfer coefficient depending on its concentration. In order to evenly disperse nano particles in the fluid, it was treated with the ultrasonic process. And Ther...

Description
Summary:This study made nano particles-dispersing alumina nano fluid to three sized copper tubes in order to identify the differences in its heat transfer coefficient depending on its concentration. In order to evenly disperse nano particles in the fluid, it was treated with the ultrasonic process. And Thermal conductivities of nanofluid are measured via the LAMBDA measuring system by transient hot wire method. And to measure the differences in the nano fluid's dispersion degree depending on its different concentrations that was measured by mean of technique using a UV device. This study found that as the diameter of copper tube size was smaller, the heat transfer coefficient got higher and the fluid's heat transfer coefficient was changed depending on the different Reynolds numbers. Based on the findings of its experiment, this study explained the alumina nano fluid's characteristics in small diameter tubes
