Paper Title:
Thermal Transpiration of Liquid in Nanoscale Channel: A Molecular Dynamics Simulation Study
  Abstract

The liquid flow in nanoscale channel under thermal gradient, or so-called thermal transpiration, is studied by Molecular Dynamics Simulation. The phenomenon was realized in two fluid systems which differed from each other in the methods for applying the temperature gradient. One used heat source and the other wall-heating. The channel was periodic and its walls consisted of two different materials: conducting, high energy wall and non-conducting slip wall. It is shown that the liquid in a periodic channel can effectively be driven by the thermal transpiration. Various characteristics of the flow are discussed that include the temperature gradient, velocity profile and liquid structure in the channel.
