摘要: In this study, the thermal conductivity and viscosity of TiO2 nanoparticles in deionized water were investigated up to a volume fraction 3% particles. The nanofluid was prepared by dispersing using ultrasonic equipment. mean diameter 21 nm. While nanofluids has been measured general conventional techniques such as transient hot-wire method, work presents application 3ω method for measuring conductivity. validated pure fluids (water, methanol, ethanol, ethylene glycol), yielding accurate values within 2%. Following validation, effective at temperatures 13 °C, 23 40 55 °C. experimental results showed that increases with an increase particle fraction, enhancement observed be 7.4% over base fluid much more than predicted Einstein model. From research, it seems is larger
