The influence of ash content on thermophysical properties of nanofluids containing nanodiamonds/graphite mixture was investigated. Rheological behaviour, thermal and electrical conductivity of this materials were measured. Two types of samples with various ash content were prepared. Each type of nanofluid was investigated with various volume fraction of nanoparticles from 0.004 to 0.023. All measurements were performed in constant temperature of 298.15 K. It was presented that ash content in this kind of nanofluids changes significantly its rheological properties. While the variation in ash content does not affect thermal conductivity of nanofluids, a big impact on electrical conductivity is reported [1].
