# Synchronized molecular-dynamics simulation for the thermal lubrication of a polymeric liquid between parallel plates

@article{Yasuda2015SynchronizedMS, title={Synchronized molecular-dynamics simulation for the thermal lubrication of a polymeric liquid between parallel plates}, author={Shugo Yasuda and Ryoichi Yamamoto}, journal={arXiv: Fluid Dynamics}, year={2015} }

The Synchronized Molecular-Dynamics simulation which was recently proposed by authors [Phys. Rev. X {\bf 4}, 041011 (2014)] is applied to the analysis of polymer lubrication between parallel plates. The rheological properties, conformational change of polymer chains, and temperature rise due to the viscous heating are investigated with changing the values of thermal conductivity of the polymeric liquid. It is found that at a small applied shear stress on the plate, the temperature of polymeric…
