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.
