摘要:This article investigates the phase-change of nanoscale liquid films on different wettability surfaces via molecular dynamics simulation, analyzes the thermal resistance between solid and liquid, investigates the thermal resistance at the solid-liquid interface and studies the mismatch between the vibrational density of states of the solid and liquid for different wettability surfaces. The results show that a liquid region of 1.4 g/cm(3) mass density always exists on the hydrophilic surface during phase-change, whereas a liquid-vapor-liked region of 0.7-0.8 g/cm(3) mass density exists on the hydrophobic surface. The thermal resistance at the solid-liquid interface of the hydrophilic surface is less than that of the hydrophobic surface. The reason is that the mismatch between the vibrational density of states of the solid and liquid of the hydrophilic surface is less than that of the hydrophobic surface.
