Abstract

The main purpose of this study is to develop a cylindrical flow cooling method in an induction heating system that is capable of producing the nanofluid. The system consists of a high frequency induction heating system, vacuum system, temperature control system, and a cylindrical curtain collector. The raw material Zn is evaporated by the high frequency induction heating system. The gas phase Zn is condensed and collected by a water cylindrical curtain collector. During the process, the gas phase Zn is oxidized. The ZnO nanoparticles were collected and suspended in de-ionized water. Through transmission electron microscopy (TEM), field emission scanning electron microscope (FESEM), X-ray diffraction (XRD) and particle size analyzer (PSA), a set of applicable parameters size can be obtained. Results show that the lower the collecting liquid temperature and the shorter the collecting distance, the smaller the nanoparticle size obtained. An aspect of UV/V is absorbency, the produced ZnO nanofluid absorbed UV when the wavelength is 360 nm to 380 nm.
