Nanoparticles suspended in traditional heat transfer fluid enhance thermal conductivity. The addition of these nanoparticles to the conventional heat transfer fluids enhances the heat transfer rate. In this work, the history of hybrid nanofluids, preparation techniques, thermoelectrical properties, rheological behaviors, optical properties, theoretical modeling and correlations, and the effect of all these factors on potential applications, such as solar energy, electronics cooling, heat exchangers, machining, and refrigeration, etc., will be discussed in detail. Future challenges and future work scope have also been included.

The information from this book enables readers to discover novel techniques, resolve existing research limitations, and create novel hybrid nanofluids, which can be implemented for heat transfer applications.
