摘要：
The structural, rheological, thermal, and dielectric properties of transformer oil-based nanofluids containing silica and silver supported on silica were investigated. Thermal conductivity was found to increase with silica concentration. The greatest enhancement was seen with silver nanoparticles supported on silica at very low weight percent of silica.
