At the sub-meter scale, capillary retention occurs when two immiscible phases flow across heterogeneous media. It happens in upstream medium, and phase retained depends on heterogeneity order system wettability. This phenomenon has a major impact oil recovery hence requires comprehension. The analysis of spatial variation saturation along flowing domain is well established. However, literature ...

The wettability is a critical property that governs the in situ fluid distribution, fractional flow, and hydrocarbon trapping porous media. This topic of immense interest to petroleum industry for exploitation unconventional resources, which have become significant source oil gas production, especially North America, Canada, China, as result advancement horizontal drilling fracking technologies...

The temporal discretization scheme is one important ingredient of efficient simulator for twophase flow in the fractured porous media. The application of single-scale temporal scheme is restricted by the rapid changes of the pressure and saturation in the fractured system with capillarity. In this paper, we propose a multi-scale time splitting strategy to simulate multi-scale multi-physics proc...

The fluid leakage channel found in contact mechanical seals belongs to the microchannel category. Thus, upon further inspection, influence of surface wettability and other factors neglected previous studies becomes obvious. porous model considering presented this paper was based on Cassie slip theory. variations length velocity under various conditions were studied relationship between apparent...
