A Perspective Review on Thermal Conductivity of Hybrid Nanofluids and Their Application in Automobile Radiator Cooling
Table 4
Advantages and disadvantages of nanocomposite-dispersed nanofluid.
Advantages
Disadvantages
A hydrophilic nanocomposite can be created by coating hydrophilic material on hydrophobic material, which is not possible with a nanoparticle mixture.
Not readily or easily available.
Better stability in comparison with mixture-based hybrid nanofluid.
Uncontrollable shape and size of particles
The heat capacity of composite nanofluid may be higher than host liquid, which is not possible for mixture nanofluid.
Inadequate theoretical models are available.
Advance enhancement in thermal conductivity and heat transfer characteristics compared to monoparticle nanofluids.
There are only a few applications in the literature, but they can be used in any application where mono nanoparticle nanofluids are used.
Nanocomposite (metallic and oxide particles)-based hybrid nanofluids are marginally less expensive than metallic-based single-particle nanofluids with same performance ratings.
Augmentation of viscosity is slightly more as compared to mono nanoparticle nanofluids.
In internal flow, pressure drop increases, which increases the pumping power slightly compared to single particle nanofluids.
