✦ Synopsis


A two-dimensional model is proposed to describe. the creeping of a liquid film against a vertical wall due to surface tension gradients. A steady solution of the governing equations is constructed through domain decomposition, scaling and matching. The creeping height is obtained as a function of the system parameters.

The enhancement of mass transfer due to this creeping film is studied. From the results an existing discussion about a "measuring stick" for the mass transfer effectiveness of a creeping film can be settled.
