Static Drainage H<sub>2</sub>/O<sub>2</sub> PEM Fuel Cells Enabled by Water Transport Plates: Pore-Scale Design and Transport Mechanisms. [PDF]
Adv Sci (Weinh)The WTP is a key component of static drainage PEMFCs, enabling cathode water removal and gas sealing through capillary forces. This work investigates the mechanisms governing WTP drainage and sealing performance and develops predictive approaches for WTP design optimization.

Stable drainage in a gravity field
Advances in Water Resources, 2022 During drainage, as a voxel of porous material is being actively invaded prior to percolation, the invading nonwetting fluid cannot be transmitted to the neighboring downstream voxel until a critical nonwetting saturation ( S n c ) is reached. This occurs when the invading fluid forms a percolating path across the voxel.

Investigating the Effects of Heterogeneity, Injection Rate, and Water Influx on GAGD EOR in Naturally Fractured Reservoirs [PDF]
Iranian Journal of Oil & Gas Science and Technology, 2013 The gas-assisted gravity drainage (GAGD) process is designed and practiced based on gravity drainage idea and uses the advantage of density difference between injected CO2 and reservoir oil.

Effect of Wettability and Adhesion Property of Solid Margins on Water Drainage
Biomimetics, 2023 Liquid flows at the solid surface and drains at the margin under gravity are ubiquitous in our daily lives. Previous research mainly focuses on the effect of substantial margin’s wettability on liquid pinning and has proved that hydrophobicity inhibits ...
