Abstract: | The assessment of proposed origins for thermal conductivity enhancement in nanofluids signifies the importance of particle
morphology and coupled transport in determining nanofluid heat conduction and thermal conductivity. The success of developing
nanofluids of superior conductivity depends thus very much on our understanding and manipulation of the morphology and the
coupled transport. Nanofluids with conductivity of upper Hashin-Shtrikman (H-S) bound can be obtained by manipulating particles
into an interconnected configuration that disperses the base fluid and thus significantly enhancing the particle-fluid interfacial
energy transport. Nanofluids with conductivity higher than the upper H-S bound could also be developed by manipulating the
coupled transport among various transport processes, and thus the nature of heat conduction in nanofluids. While the direct
contributions of ordered liquid layer and particle Brownian motion to the nanofluid conductivity are negligible, their indirect
effects can be significant via their influence on the particle morphology and/or the coupled transport. |
