In this paper, a hybrid method combining molecular dynamcis (MD) and finite volume method (FVM) based on LAMMPS and OpenFOAM is developed. The convective heat transfer of water coarse-grained by mW model flowing through a nanochannel is simulated by using the hybrid method. The characteristics of temperature distribution is analyzed. The axial heat conduction plays a significant role in the convective heat transfer at nanometer scale. Based on the comparison of convective heat transfer between smooth and rough surfaces, it is found that the roughness in the solid surface can enhance the heat transfer, mainly in the middle part of the channel.
