Models for evaluating the saturation in Liquid Composites Molding: a numerical journey

The main aim of this work is the proposal of a numerical procedure for solving the saturation equation in Resin Transfer Molding process simulation. In order to analyze in more detail the progressive impregnation of a fibrous preform by a fluid resin, the numerical model here proposed considers the flow through a partially saturated medium, including the dependence of permeability on the saturation degree. The main numerical issues will be discussed.
