Fluids can move or flow in many ways. . In . steady flow. the velocity of the fluid particles at any point is constant as time passes. . Unsteady flow. exists whenever the velocity at a point in the fluid changes as time passes. Series. Presents a Seminar. . Physics-based Models of Multiphase Flow in. Porous Media. The traditional model of two-phase flow in porous media is a heuristic formulation that is typically proposed as an extension of Darcy’s law for single-phase flow. In this extension, the capillary pressure is considered to enter the model as a function of saturation. Here we show that, in fact, the quantity identified as capillary pressure is incorrectly identified. Consideration of the inter-pore behavior and distribution of phases in porous media in experimental and computational studies confirms the inadequacy of the standard model.

In laminar flow, the fluid moves smoothly in orderly layers, with little or no mixing of the fluid across the flow stream. . With laminar flow, there can still exist changes in velocity as the friction of the wall slows the layers closest to the wall, while the flow in the centre of the pipe moves at a faster pace. . : .
