Abstract

The goal of these studies ended up being synthesize copper oxide nanoparticles, that have been then put on prepare CuO–water nanofluid, having a spinning disk reactor (SDR). The precursors of copper oxide were first prepared within the continuous mode utilizing a liquid–liquid reaction using copper (II) sulfate pentahydrate and sodium carbonate as reactants. Then, the precursors were calcined around 500 °C to obtain copper oxide nanoparticles. The final results of operating variables, including disk rotation speed, reactant concentration, and liquid flow rate, about how exactly big the copper oxide nanoparticles were investigated. Smaller sized sized sized copper oxide particles were acquired under lower reactant concentrations and greater disk rotation speeds. What size the acquired primary particles of copper oxide ranged between 20 and 30 nm observed within checking electron microscope when compared with number mean size 40–50 nm with various particle size analyzer. Finally, a CuO–water nanofluid was ready for growing the thermal conductivity using various CuO contents and surfactant concentrations.

Graphical Abstract

Copper (II) oxide nanoparticles with size 20–30 nm were synthesized having a spinning disk reactor. A CuO–water nanofluid was ready for growing the thermal conductivity using various CuO contents and surfactant concentrations.

Research Highlights

A spinning disk reactor (SDR) was requested preparing nanoparticles. 20–30 nm CuO nanoparticles were synthesized for nanofluid application.

Reactant concentration is a crucial factor which affects the CuO particle size distribution.
