Specific heat measurement
WebAbstract This paper presents the specific heat measurements of three nanofluids containing aluminum oxide, zinc oxide, and silicon dioxide nanoparticles. The first two are dispersed in a base fluid of 60:40 by mass of ethylene glycol and water (60:40 EG/W) and the last one in deionized water.
