Abstract

Molecular dynamics simulations are used to investigate the dynamics of fluid flow into empty cylindrical pores with diameters between 1.5 and 5 nm. Model system parameters are chosen to represent xenon in silica pores. The principal data collected are the amount of fluid in the cylinders and the density profile of the fluid. The effects of both pore diameter and fluid temperature are considered. The temperature is found to have little effect on the penetration of the fluid into the pore until temperatures close to the critical point are reached. The cylinder diameter has a substantial effect, and for diameters ≥2 nm, the rate of fluid flow into the pore is proportional to its cross-sectional area. Last, at subcritical temperatures in all but the smallest (1.5 nm) cylinders, the total amount of fluid in the cylinder is observed to grow as the square root of the time.

  The spontaneous imbibition of liquid in nanopores of different roughness is investigated using coarse grain molecular dynamics (MD) simulation. The numerical model is presented and the simplifying assumptions are discussed in detail. The molecular-kinetic ...
