Simulation of two-dimensional flows in micropores
- Tulane Univ., New Orleans, LA (United States). Dept. of Mechanical Engineering
An approach based on the Molecular Dynamics is used to simulate liquid flows in two-dimensional micropores and to obtain the steady-state characteristics of the flow. The mass flux of the liquid is taken as a constraint condition. Therefore, the driving force is introduced according to the Gauss least-constraint principle. The liquid molecules are considered as spheres with the same mass and density as water molecules. The interaction between the liquid molecules is of the Lennard-Jones type. Pure liquid flows and solid-liquid flows are simulated numerically. It is found that the velocity profile of the pure liquid flow matches very well the analytical solution of the plane Poiseuille flows. It was observed that larger particles will tend to flow closer to the walls. Also that the existence of the large particle makes the liquid flow somewhat faster in the center of the pore. Significant velocity slip was observed between the larger particle and the liquid.
