Resumen:
Capillary imbibition is appealing as a technique to drive fluids in a domain, as it can beleveraged to obtain predictable flows that do not require the use of pumps. A promising application ofcapillary imbibition in porous media lies within the growing field of paper-based microfluidics, which isenabling the development of affordable and autonomous portable devices for use in clinical diagnostics,biomedicine, and the environmental sciences, among other disciplines. Simulations of flows in porousmedia, including supporting software, have mostly focused on problems at scales that are several ordersof magnitude larger, such as models of groundwater systems and oil extraction processes. In thiswork, we use the porousMultiphaseFoam library within the OpenFOAMRsimulation platform in orderto model and solve cases of capillary imbibition in complex paper structures with applications in biotechnology.The simulation model is validated, in terms of the resulting flow rates and shapes of the wettingfronts, against problems that have established analytical/empirical solutions, before being used to solvecomplex cases of practical interest.
