A simplified mathematical modelling is presented, which captures these regimes. The analysis allows to characterise the corresponding crossovers between the limiting cases, and generalise the dynamics to imbibition when there is an external forcing.
Our work paves the way into experimental scenarios of similar systems, like SLIPS or LIS, and also towards characterisation of lubricant-coated surfaces in more general channel geometries like wegdes or sinudoidal shapes.
