Abstract


A simple and general method to calculate the equilibrium heights of a liquid that penetrates spontaneously, due to capillarity, into a corrugated Hele-Shaw cell is presented. A cosine-like corrugation was imposed on each internal face of the plates that made the cell and periodic channels were generated. It were found complex equilibrium heights which allow to evaluate the volumes of absorbed liquid or expelled gas. Equilibrium heights were also evaluated in corrugated tilted cells.

Keywords
