Nanofluids (NFs) are suspensions of nanoparticles in a fluid with
improved characteristics at low concentrations, gaining importance in various
technical sectors like automotive, healthcare, power plant cooling systems, and
computing equipment. Better heat transfer capacities, thermal conductivities,
and stability can be counted among the advantages that NFs can provide.
Whereas, nanoparticle addition may also raise viscosity, albeit increasing
thermal conductivity, curbing their thermal advantages. Stability and
temperature behavior are crucial issues. Hybrid nanofluids (HNFs) are highly
sought after due to their superior thermophysical properties compared to
conventional base fluids. To produce these high-performance heat transfer
fluids, two or more different nanoparticles are suspended in a base fluid. By
highlighting their remarkable characteristics and uses, this research reveals
the great potential of HNFs, especially in thermal operations. Binary and
ternary thermophysical properties, including heat transfer rate, heat transfer
coefficient, friction factor, thermal performance factor, Nusselt number, heat
transfer efficiency, zeta potential, stability, thermal efficiency, isobaric
heat capacity, and specific heat capacity, have been used to categorize the
literature. In addition, the present work scrutinizes studies related to HNFs,
particularly those focused on thermal conductivity and viscosity, and covers
ingredients such as nanoparticle type, concentration, temperature, and
surfactant use for the purpose of preventing sedimentation and agglomeration.
Moreover, the paper delivers an improved investigation on NFs’ properties,
especially involving their physical and rheological aspects in the context of
heat transfer enhancement.
