Tayyab Raza Shah –
In the natural world, TiO 2 exists in three different crystalline forms as anatase, brookite, and rutile. Eventually, the environmental and economic advantages of these systems are presented. Subsequently, economic and ecologic gains of using binary nanofluids in solar energy systems are presented. Pivotal analysis of past studies revealed that hybrid nanofluids are highly effective heat transfer media owing to their elevated thermal and physical characteristics. A critical review more.
However, nanofluid can also be prepared directly by using a liquid chemical method or vapor deposition technique VDT. Heat TransferNanofluidsand Thermophysical properties of nanofluids.
To date, enormous evaluative work has been conducted on hybrid-nanofluids to explore their heat transfer and physical features. Reviewed studies have reported remarkable enhancement in power output and efficiency of these systems. Considering the thermal features and stability period, potential of different hybrid-nanofluids for future work has been discussed in the concluding section of this paper.
Nanoparticles are not used directly in many heat tyyab applications, and this provides a major challenge to researchers to advance towards stable nanofluid preparation methods. Short stability lasting period of hybrid-nanofluid has faded the feasibility of their commercial use despite of tempting features like elevated thermal hayyab rheological characteristics.
Diverse range of solar energy conversion systems has been employed to convert solar energy into desired useful form. Application of hybrid nanofluids in solar energy systems as working fluid has turned out to be very gainful in terms of performance, owing to distinct thermal transportation characteristics of hybrid nano-fluids. But the sole issue associated with these fluids is their instability.
Brief summary of the findings of most recent studies is presented in this review.
