Influence of Slip Flow at Fluid-solid Interface upon Permeability of Natural Rock

The flows involving CO2 sequestration encounters pores of very small size usually in micro-meter range. At this scale, various small-scale flow effects associated with the fluid-solid interaction governs the hydrological properties. Hence, realizing the importance of appropriate boundary condition when dealing with the small scale flow is of extreme importance. One such effect is the occurrence of slip at the fluid-solid interface. The implementation of slip boundary condition, in lattice Boltzmann framework, is discussed in the present study. The effect of slippage on the bulk properties is obtained in channel flow using the slip boundary condition. Further, a homogeneous porous media is considered to show the effect of slip flow on bulk as well as local flow properties.
