TL;DR

This study uses Landauer-Buttiker theory to analyze plasmon-mediated heat transfer in nanoparticle arrays and finds near-field interactions have minimal impact on nanofluid thermal conductivity.

Contribution

It provides a theoretical and numerical analysis of plasmonic heat transfer in nanofluids, revealing the limited role of near-field interactions.

Findings

Near-field interactions have negligible effect on nanofluid thermal conductivity

Plasmon modes contribute minimally to heat transfer in nanoparticle arrays

Numerical simulations support the limited influence of near-field effects

Abstract

Using the Landauer-Buttiker theory we calculate the thermal conductance associated to plasmons modes in one dimensional arrays of nanoparticles closely spaced in a host fluid. Our numerical simulations show that the near-field interactions between particles have a negligible effect on the thermal conductivity of nanoparticles colloidal solutions (nanofluids).
