The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Experimental measurements of saturation overshoot on infiltration (2004, background): “[32] Along these lines, it is noted that in discrete network models of unsaturated flow where cells are either filled or unfilled with water, saturation overshoot occurs naturally [Glass and Yarrington, 1996; Hughes and Blunt, 2000, 2001; Glass and Yarrington, 2003].”
Direct simulations of two-phase flow on micro-CT images of porous media and upscaling of pore-scale forces (2014, background): “Pore-network models have been extensively used to study multiphase flow through porous media [2,6,10,11,15,16,27,37, 39,51,55].”
Non-equilibrium effects in capillarity and interfacial area in two-phase flow: dynamic pore-network modelling (2010, background): “Valvanides et al. (1998) and Al-Gharbi & Blunt (2005) have assumed triangular cross-sections, whereas Mogensen & Stenby (1998), Hughes & Blunt (2000), Singh & Mohanty (2003) and Gielen et al. (2005) have assumed cubic pore bodies and parallelepiped pore throats.”
Pore‐scale displacement mechanisms as a source of hysteresis for two‐phase flow in porous media (2016, background): “The importance of NWP topology for imbibition has been stressed early on [Lenormand et al., 1983; Wardlaw and Yu, 1988; Hughes and Blunt, 2000].”
