摘要：

In a well-dispersed nanofluid with strong cluster-fluid attraction, thermal conduction paths can arise through percolating amorphouslike interfacial structures. This results in a thermal conductivity enhancement beyond the Maxwell limit of 3 phi, with phi being the nanoparticle volume fraction. Our findings from nonequilibrium molecular dynamics simulations, which are amenable to experimental verification, can provide a theoretical basis for the development of future nanofluids.
