It introduces a novel method of increasing nanofluid thermal conductivity using external oscillating forces without inducing particle aggregation.

Findings

Thermal conductivity is significantly increased under oscillating force fields.

Enhancement occurs without nanoparticle cluster formation.

Radio frequency and microwave forces are effective in this process.

Abstract

The thermal conductivity of nanoparticles colloidal suspensions, submitted to the action of an external force field has been calculated by non equilibrium molecular dynamics simulations. For driven forces in the radio frequency and microwave ranges, we show that the thermal conductivity of nanofluids can be strongly enhanced without cluster formation.
