Chih-Hung Lo and Tsing-Tshih Tsung

Abstract

This study involves the use of copper oxide nanofluid produced by the Submerged Arc Nanoparticle Synthesis System (SANSS) to investigate temperature effect on particle suspension of copper oxide nanofluid. The purpose is to understand the deposition state feature of copper oxide nanofluid in a lower-than-room-temperature work environment and to motion behavior of suspended nanoparticle and to analyze its mean secondary particle size. The amount of the nanoparticle was also varied. The relationship between temperature and particle size was investigated. An analytical method to predict the results was introduced. It was concluded that particle size change stable as the temperature decrease due to Brownian motion of retard. The change of environmental temperature can affect copper oxide nanofluid stability in application. Hence, the phenomenon is important when the copper oxide nanofluid in a lower-than-room-temperature of work environment.
