Capillary filling and Haines jump dynamics using free energy Lattice Boltzmann simulations
详细信息   
摘要
•Capillary filling a. Correct dynamics in the limit of large times for high and low viscosity ratios (1. scaling of length with time and 2. variation of the dynamic contact angle) b. Correct dynamics in the limit of small times (two successive regimes of length vs time precede the Lucas-Washburn regime)•Haines jump events a. Associated with both drainage and capillary filling dynamics b. Non-local, cooperative events with imbibition occurring during drainage of a pore body in the surrounding pore throats. This leads to fluid redistribution in the area of the surrounding draining pore. c. Role of the Ohnesorge number in determining draining times. d. Role of the Ohnesorge number in identifying the type of pore filling dynamics that will occur.
