Description
We study imbibition and drainage through a localised constriction in a Hele-Shaw cell, as a model system designed to gain insight into multiphase displacements in porous media. In this context, the detailed quantitative response of the non-local interface dynamics to localised defects at nonzero flow rate is a key feature that remains poorly understood. Combining experiments, numerical simulations, and theory, here we show that steady conformations of a moving two-phase interface are strongly affected by the imposed flow rate, leading to asymmetric imbibition–drainage hysteresis cycles. The present results show also that medium heterogeneities can lead to long fluid filaments, and even pinch-off scenarios and fluid trapping, under linearly-stable Saffman-Taylor conditions, an insight that should be considered in practical applications of multi-phase flows through disordered media.
