KINETIC MODELS FOR NANOFLUIDICS

One-dimensional flows of a simple liquid through nanochannels are studied by numerical solution of Enskog-Vlasov kinetic equation which provides and approximate but accurate description of a fluid whose molecules interact through Sutherland potential. The accuracy of the results is assessed by comparisons with molecular dynamics simulations. The deviation from hydrodynamic behavior is studied as a function of relevant flow parameters. Finally, it is shown that the model allows a natural extension capable of describing fluid-wall interaction by the same formalism.
