Flow behavior of gas confined in nanoporous shale at high pressure: Real gas effect

摘要: Abstract Understanding and controlling the gas flow at nanoscale has tremendous implications in fields of separation science, catalytic reactions, energy storage, conversion extraction. However, behavior is significantly different from that occurring larger scales. In this work, we focus on a real effect, stemming strong intermolecular interaction force high pressure an un-negligible molecule volume nanoscale, through nanoporous shale. An analytical unified model developed validated with published results Lattice-Boltzmann equation experiments. This covers all mechanisms, including viscous flow, slip transition captures which enhances capacity ready-to-use tool for fast accurately modeling nanopores, provides basic foundation numerical simulation production prediction shale reservoirs.
