Abstract
The present paper focuses on an experimental study of pool boiling characteristics of ceriumoxide (CeO2, ceria) nano-suspension on a horizontal flat copper surface at atmospheric pressure. The nanofluidsuspension is prepared by a two-step method and stabilized using Na-citrate, pH setting and ultrasonic vibrationas well. The effect of applied heat flux to the boiling surface on pool boiling heat transfer coefficient (HTC) ofcerium oxide nanofluid is experimentally examined and briefly discussed. The results illustrate that the pool boilingHTC increases with using cerium oxide nanofluid as working fluid. Also, the results show that the critical heat fluxfor cerium oxide nanofluid having 0.1 vol.% nanoparticle concentration improves up to 103% compared with thedeionized water.
