This is not necessarily a simple process! Creating … See more In this blog post, we discussed how we can use simulation to derive the macroscale properties of flow through porous media — … See more Let’s now take a quick look at the pore-scale flow example, which solves the fully resolved pore space geometry. We can use the postprocessing tools within COMSOL Multiphysics … See more WebThe simulation results on Core 1 , Core 3 , and Core 6 express that the pressure field and the velocity field are opposite in direction, which results in the inability to calculate the …
WebNov 25, 2024 · The permeability of the semi-solid state is important for the compensation of volume shrinkage during solidification, since insufficient melt feeding can cause casting defects such as hot cracks or pores. Direct measurement of permeability during the dynamical evolution of solidification structures is almost impossible, and numerical … Webpermeability, capacity of a porous material for transmitting a fluid; it is expressed as the velocity with which a fluid of specified viscosity, under the influence of a given pressure, …
WebPermeability is defined for pore fluid flow. Forchheimer's law According to Forchheimer's law, high flow velocities have the effect of reducing the effective permeability and, therefore, “choking” pore fluid flow. As the fluid flow velocity reduces, Forchheimer's law approximates the well-known Darcy's law.
