The　solid-liquid　interfacial　thermal　transport　depends　on　the　physical　properties　of　the　interfaces,　which　have　been　studied　extensively　in　open　literature.　However,　the　fundamental　understanding　on　the　mechanism　of　the　solid-liquid　interfacial　thermal　transport　is　far　from　clear.　In　the　present　paper,　heat　transfer　through　solid-liquid　interfaces　is　studied　based　on　the　non-equilibrium　molecular　dynamics　simulations.　It　is　shown　that　the　interfacial　heat　transfer　can　be　enhanced　by　increasing　interfacial　coupling　strength　or　introducing　the　nanostructured　surfaces.　The　underlying　mechanism　of　the　interfacial　thermal　transport　is　analyzed　based　on　the　calculation　results　of　the　heat　flux　distribution,　potential　mean　force,　and　the　vibrational　density　of　states　at　the　interfacial　region.　It　is　found　that　the　interfacial　thermal　transport　is　dominated　by　the　kinetic　and　virial　contributions　in　the　interface　region.　The　enhancement　of　the　interfacial　heat　transfer　can　be　attributed　to　the　fluid　adsorption　on　the　solid　surface　under　a　strong　interfacial　interaction　or　by　the　nanostructured　solid　surfaces,　which　reduce　the　mismatch　of　the　vibrational　density　of　states　at　the　solid-liquid　interface　region.
