We investigate a two-dimensional network simulator capable of modeling different time dependencies in two-phase drainage displacements. In particular, we focus on the temporal evolution of the pressure due to capillary and viscous forces and the time dependence of the interface between the two liquids. The dynamics of the capillary effect are taken into account and we report on high accuracy pressure measurements. Moreover, the simulator includes important features in drainage, like burst dynamics of the invading fluid and simultaneous flow of two liquids in a section of a tube. The validity of the model is checked by comparing simulation results with well known experimental properties in drainage displacement.
