In the study of porosity, it is assumed a two-dimensional physical model which consists of a simplified version of a three-dimensional physical model of a fluidic flow with transport of species through a cross-section of a pipe with a wall dotted of porosity. Therefore, a study of the effect of that same wall on that same flow. On the other hand, the spatial study involves an exhaustive simplification of a three-dimensional organic and complex spatial-geometrical physical system human head + mask to a two-dimensional more friendly computational physical system.
Finally, by combining these two studies it is
possible to have a more realistic insight of the effects of the topological and
material’s properties of the mask over all physical system.
