In the present study, we conducted nonequilibrium molecular dynamics simulations in order to investigate influences of the adsorption layers of the liquid around a nanoparticle on the effective thermal conductivity of liquid with nanoparticle suspension. We adopted liquid systems with nanoparticle suspension between two solid walls and obtained the effective thermal conductivity based on the Fourier’s law imposing a temperature difference between the two solid walls. Contributions of the adsorption layer to the effective thermal conductivity were investigated quantitatively, and the results showed that the thermal conductivity in the adsorption layer increases with the increase of the interaction intensity between the nanoparticle and the liquid.
