Modelización de la tensión superficial de surfactantes no iónicos

Modelización de la tensión superficial de surfactantes no iónicos

Abstract

En el presente trabajo se realiza un tratamiento cuantitativo de la tensión superficial dinámica a través de diferentes aproximaciones matemáticas, considerando un mecanismo controlado por difusión. El modelo clásico se ha modificado para que describa las condiciones experimentales de forma más precisa al considerar un dominio de difusión finito. Se han fijado los límites del dominio de forma que la concentración en esta región permanezca constante tras la adsorción en la interfase aire-agua, de forma que el número de monómeros sea treinta veces superior al adsorbido en la superficie. La restricción de difusión finita ha sido empleada en un modelo unidimensional y en un modelo axisimétrico, siendo este último el más preciso y el que necesita de un dominio de difusión más pequeño, debido a su mejor representación de las condiciones experimentales.
