TY - JOUR T1 - A New Boundary Condition for Three-Dimensional Lattice Boltzmann Simulations of Capillary Filling in Rough Micro-Channels JO - Communications in Computational Physics VL - 5 SP - 1284 EP - 1292 PY - 2011 DA - 2011/05 SN - 9 DO - http://doi.org/10.4208/cicp.141009.241110s UR - https://global-sci.org/intro/article_detail/cicp/7551.html KW - AB -

A new boundary condition, aimed at inhibiting near-wall condensation effects in lattice Boltzmann simulations of capillary flows in micro-corrugated channels, is introduced. The new boundary condition is validated against analytical solutions for smooth channels and demonstrated for the case of three-dimensional microflows over randomly corrugated walls.
