Outline of Final Research Achievements

The synchronized molecular dynamics simulation via macroscopic heat and momentum transfer is developed for the thermal lubrication problems. This method is applied to the lubrication of a polymeric liquid between fast moving parallel plates. The rheological properties and conformation of polymer chains coupled with the local viscous heating are investigated with a non-dimensional parameter, i.e., the Nahme-Griffith number, which is defined by the ratio of the viscous heating to the thermal conduction at the characteristic temperature required to sufficiently change the viscosity. The results also clarify a new transitional phenomenon in the conformational dynamics of polymer chains due to the competition of the flow and thermal agitation.
