Threshold pressure experiment of liquid flows through nanochannels and tight cores

چکیده

Abstract Compared with low-permeability oil reservoirs, tight reservoirs have more nanopores, complex pore structure, and obvious nonlinear seepage characteristics. Under the macro-scale channel flow, influence of micro-forces is often ignored, but micro-nano-scale become main factors affecting flow. The flow different from requires force between fluid micro-nano tubes. article conducts threshold pressure experiment nanochannels cores, results show that exists a under liquid flows through cores. gradient in micro-nanochannels analyzed, it found nature diameter pores affect micro tube; core experiments prove core. are permeability experimental fluid.

Water Flows in Copper and Quartz Nanochannels

Numerous experimental results indicate, that the microscale flows are essentially different from flows in large scale [1], [2]. The continuum Navier-Stokes approach, suitable for large sale flows, is not applicable to small scales. At the same time, however, there exists an extension of the Navier – Stokes approach, also based on the assumption of a continuous medium – the micropolar fluid mode...

Formation of liquid menisci in flexible nanochannels.

In this paper we analyze the characteristic shape of the liquid meniscus at the fluid air interface in nanochannels of less than 80 nm height capped by a flexible membrane. Because of the induced negative pressure difference between the liquid pressure and the pressure outside, the 0.18 microm thin membrane on top of the channels bends downward. This elastocapillary equilibrium between the surf...
