石墨烯具有高热导率的特点，在传热领域有较好的应用前景,石墨烯导热理论及其应用研究具有重要意义。文中利用分子动力学方法，研究了石墨烯在固液界面间的传热规律，并探究了不同壁面温度下，石墨烯传热层对固液界面热阻及流动特性的影响。结果表明，在静态流体中,单层石墨烯传热层会显著降低固液界面温度阶跃和界面热阻，壁面温度越高，石墨烯层对界面热阻的降低效果越明显，降低幅度最高分别可达48%和45.9%。对流体区域施加外力使流体流动，结果显示，由于石墨烯与液氩的相互作用力弱于铜壁面，导致固液壁面处速度滑移程度增大，且石墨烯具有比表面积大的特点，近壁面处分子数增多，热运动增强，使近壁面处的温度阶跃增大。

With the characteristics of high thermal conductivity, Graphene has a good application prospect in the field of heat transfer, and it’s of great significance to study graphene thermal conductivity theory and application. This paper investigated the heat transfer behavior of graphene at the solid-liquid interface by using the molecular dynamics method, and studied the effect of graphene heat transfer layer on the wall-liquid interface thermal resistance and flow characteristics under different wall temperatures. The results show that a single graphene heat transfer la-yer can significantly reduce the temperature jump of the solid-liquid interface and the interfacial thermal resistance in a static fluid. The higher the wall temperature is, the more significant the reducing effects of the graphene layer on the interfacial thermal resistance will be. The a reduction rate is as high as 48% and 45.9%, respectively. The external force was applied to the fluid to keep fluid flowing, and the results show that, as the graphene-fluid inte-raction is weaker than the wall-fluid interaction, the velocity slip at the solid-liquid wall is increased. And graphene has the feature of a large specific surface area, so the number of molecules near the wall is increasead, and the thermal motion and the temperature jump near the wall is enhanced.
