..., the inertial term is ignored in order to create a simplified diffusion equation model. It is not zero. Furthermore, in the classic diffusivity derivation ( Earlougher 1977 ), the capillary entry pressure is assumed to be small and hence neglected. It is also not zero. By excluding these terms in the classic...
