Drying and impurity deposition in porous materials
Abstract: As a filter (eg: in a washing machine) or a textile (eg: a raincoat) dries, any dirt or impurities in the water are left behind within the porous structure. It’s important to know where the dirt ends up because this impacts the future efficacy of the filter or raincoat: does it deposit uniformly throughout the porous material, or concentrate at the surface? Can the accumulating dirt ever clog the porespace entirely, and if so, how can we avoid this? To investigate, we derive, analyse, and solve a model for the motion of an evaporation front through a porous material, and the coupled accumulation, transport, and deposition of the dirt.
