In this report, we have shown that gold nanofluid containing networked gold particles have much more enhancement (approximate to 35%) in thermal transport in comparison to gold nanofluid containing conventional spherical gold nanoparticles under similar condition and loading fraction. This shows that structure or shape of the loading materials has very important effect on thermal conductivity of a nanofluid. Connected structure helps to increase the rate of heat transfer in the medium. The gold nanofluid having network of gold nanoparticles is synthesized in a single step process by pulsed laser ablation. The nanofluid (containing gold network) is stable and in addition to enhanced thermal conduction (compared to conventional gold nanofluids) shows no enhancement of viscosity unlike that seen in many nanofluids containing elongated nanomaterials (like cylinder or ellipsoids) in the dispersed phase which limits the use of nanofluids containing these kind of elongated structures in thermal transport though they have enhanced thermal conductivity than the conventional nanofluids (containing spherical nano particles). We synthesized and investigated the thermal transport in nanofluids containing network of Au nanoparticles instead of elongated nanomaterials in the dispersed phase as it retains the advantage of the spherical nanoparticles yet utilizes the enhanced heat transport by the network structure.
