Visualizations of gas-liquid two-phase flows in simulated porous media microchannels were performed to understand the dynamics in porous media. The channel consists of two junctions that simply simulated a porous flow-field. Two types of flow patterns, (i) water single phase flow at the one side and two-phase flow at the other side and (ii) two-phase flow at both channels, were observed at the simulated porous region. Pressure differences were estimated for both flow patterns and the results show that lower pressure drop is possible for the former pattern. It is expected that providing water single phase pass can reduce pressure loss in porous media.
