The pressure drop in microfluidic minichannels filled with porous media formed by square arrays of microcylinders is investigated. We investigate the problem by combining the Brinkman equation and existing models for permeability of regular arrays of cylinders to calculate the pressure drop of the studied geometries theoretically. In order to verify our theoretical analysis, a soft lithography ...

The investigation of a two-phase flow in porous media has significant implications for wide range applications. Previous research focused on exploring the variations and phase fields using experimental numerical methods. However, complex structure introduces many uncertainties that can impact outcomes. In recent years, some scholars have tried to study dynamic mechanics through typical structur...
