Abstract

Se presenta un método simple y general para calcular las alturas de equilibrio de un líquido que penetra espontáneamente, por capilaridad, en una celda de Hele-Shaw vertical y corrugada. La corrugación se impuso sobre cada una de las paredes interiores de las placas que forman la celda como funciones coseno y de esta forma se generan canales periódicos verticales. Se encuentra que esta corrugación determina complejos per.les de equilibrio que pueden ser integrados para estimar los volémenes de líquido absorbido, o del aire (gas) desalojado. Se discuten también resultados para celdas corrugadas con una inclinación respecto a la vertical. 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.
