Spreading of fluids in narrow channels


In recent years, the field of nanofluidics attracted much experimental and theoretical interest. The main theoretical challenge is to understand the dynamics of fluids confined in nanoscale devices, where the atomistic details of the setup play an important role. Recently, we have proposed a stochastic model in order to investigate the spreading of fluids in narrow slit-like channels, connected at their ends with two reservoirs of particles at different chemical potentials. Possible generalizations of this model, including driving forces acting directly on the fluid particles, will also be presented. Even in the most simple case, in which the fluid-fluid interaction is restricted to hard-core interactions between particles, a rich dynamical and steady-state behavior is found.
