| 2rxbn_v1 | Quantification of non-linear multiphase flow in porous media | We measure the pressure difference during two-phase flow across a sandstone sample for a range of injection rates and fractional flows of water, the wetting phase, during an imbibition experiment. We quantify the onset of a transition from a linear relationship between flow rate and pressure gradient to a non-linear power-law dependence. We show that the transition from linear (Darcy) to non-linear flow and the exponent in the power-law is a function of fractional flow. We use energy balance to accurately predict the onset of intermittency for a range of fractional flows, fluid viscosities and three rock types, reconciling several literature datasets. | 2020-08-20T14:52:14.063702 | 2021-02-08T21:35:19.895019 | 2020-08-20T19:15:55.465880 | eartharxiv | 0 | withdrawn | 1 | 1 | https://doi.org/10.31223/osf.io/2rxbn | GNU Lesser General Public License (LGPL) 2.1 | fluid dynamics; multiphase flow; porous media | ["fluid dynamics", "multiphase flow", "porous media"] | Yihuai Zhang; Branko Bijeljic; Ying Gao; Qingyang Lin; Martin J.
