【 摘 要 】

The modified pseudopotential Lattice Boltzmann model has been used to study the motion and morphology of a single rising bubble in porous media. Effects of the wettability at solid-fluid interfaces and non-dimensional number Eo on bubble rising dynamics are illustrated in this study. The wettability of the solid surface is modeled by employing an interaction force between the solid wall and the fluid.
