A PROCESS FOR IMPROVING THERMAL CONDUCTIVITY OF TRANSFORMER OIL BY NANOPARTICLE ADDITION

摘要

The present invention relates to compositions of nanofluids containing a thermally transfer fluid and ceramic nanoparticles. The nanofluid of the present invention is based on a hydrophobic fluid such as transformer oil and the nanoparticles suspended are multiwalled carbon nanotubes (MWCNT), copper oxide (CuO) and cerium oxide (CeO2). The invention further relates to a method of dispersing the nanoparticles in the base oil and surface active agents to form a stable suspension. The enhancement O thermal characteristics of these oil based nanofluids is determined and validated.
