It is found that increasing the fluid–solid interaction can effectively enhance the capillary flow, and the capillary velocity is proportional to the fluid–solid interaction parameter Σ.

In continuum mechanics the flow velocity in fluid dynamics, also macroscopic velocity in statistical mechanics, or drift velocity in electromagnetism, is a vector field used to mathematically describe the motion of a continuum. The length of the flow velocity vector is the flow speed and is a scalar. It is also called velocity field; when evaluated along a line, it is called a velocity profile (as in, e.g., law of the wall).
