Based on the generalized distribution of the temperature field, an improved model for the thermal conductivity of nanofluid has been derived. The impact of particle size and Brownian motion is modeled through the effective volume fraction, based on particle radius. In the special case, the generalized relationship reduces to the classical Maxwell model. On the other hand, the effect of Brownian movement is equivalent to increasing the effective volume fraction of nanoparticles. The effective radius of the nanoparticle is proposed, where the switching time and the equivalent volume fraction depend on the Brownian velocity of the nanoparticles. Considering the above two effects, an effective model is obtained. Comparison of thermal conductivity for Al 2 O 3 -water nanofluid is made between the present model and several theoretical models. Theoretical predictions on CuO-water nanofluid, ZnOTiO 2 hybrid nanofluids and MWCNTs nanofluid are also verified against experimental data.

View full text Add to dashboard Cite

Nanofluids are suspension of highly conductive nano‐sized particles in conventional fluids that may be applicable as ultrafast cooling agent to extend the thermal performance of cooling devices. However, before considering the feasibility as coolant for high heat flux components, a thorough investigation of the long‐term stability of nanofluids is of paramount importance. Preparation of extremely stable nanofluids has become one of the main technical challenges. The present contribution aims to summarize the recent developments in the preparation, characterization, and stabilization of nanofluids based on the information available in literatures. Lastly, existing needs and attainable solution to challenges, leading to the upcoming research in the development of highly stable nanofluids, are discussed.
