Poreennetwerkmodellen

Poreennetwerkmodellen are computational tools used to simulate the flow and transport of fluids and solutes within porous materials. These models represent the complex pore structure of a material as a network of interconnected pores and throats. Pores are the larger void spaces, while throats are the constrictions that connect them. The geometry and connectivity of this network are crucial for accurately representing the material's properties.

These models typically discretize the porous medium into a graph-like structure. Each pore and throat is assigned specific properties, such as volume, diameter, and length. Fluid flow and solute transport are then simulated by applying physical laws, such as Darcy's law for flow and advection-diffusion equations for solute transport, across the network elements. The behavior of the fluid or solute is determined by the interactions within this network.

Poreennetwerkmodellen are valuable for understanding phenomena like groundwater flow, oil and gas recovery, contaminant transport, and filtration processes. By varying the network characteristics, researchers can investigate how pore structure influences macroscopic properties like permeability, porosity, and dispersion coefficients. The accuracy of the model depends heavily on how well the network structure represents the actual pore space of the material. Advances in imaging techniques, such as micro-CT scanning, have greatly improved the ability to reconstruct realistic pore networks for modeling.
