Description
Summary:The impact of doping electrical insulating fluids with nanoparticles on the thermal characteristics of the resulting nanofluids and heat transfer for cooling high-power transformers is covered in this study. The base fluid in this case was the synthetic ester. It investigated how adding Barium titanate (BaTiO3)nanoparticles to dielectric fluids affected thermal characteristics, including convection and thermal conductivity. Comparisons were made between the cooling performance of basic fluids and nanofluids. An examination of the Rayleigh and Nusselt values confirms this comparison. The effects were represented as functions of the solid volume particle from the nanoparticles (0 ≤ φ
