Abstract: The modeling of spontaneous imbibitions of a liquid into porous wicks which are made from natural fibers has been investigated in the current research. There has been numerous numbers of mathematical models to predict the wicking properties. The application of all the models depends on some factors such as the microstructure of the wick, porosity, wicking liquid and etc. Lucas-Washburn equation is one of the initial and old wicking models to predict the height of liquid front as a function of time. Darcy’s law as an applicable model is based on the movement of the liquid in the wick with a sharp front. However, the sharp-front model is unable to explain region of partial saturation. Richard’s equation covers this drawback and predicts the absorbed liquid-mass into the wick as function of time. In this research we overview the application of theses famous theoretical models and their applicability.
