Investigation on stability of tri-hybrid nanofluids in waterethylene glycol mixture

Nanofluid is a suspension of liquid containing metal or non-metallic nanoparticles of typical size (1-100 nm) dispersed into the base liquid. Hybrid or composite nanofluids is considered an extension of research work for single nanofluids, which can be carried out through a combination of two or mor...
