Numerical modeling and experimental analysis for flows in a homogeneous porous medium through soils

The oil companies study the movement of groundwater for future searches of drilling fields or open-pit excavations, it has also been used for the purification of water by means of sand filters. The objective of this research was to determine the behavior of the water flow in a porous medium (sand). One of the laws most used to understand this phenomenon is Darcy's law, which says that the flow through the porous medium is directly proportional to the pressure differences and inversely proportional to the distance that the fluid must pass through. It was evaluated: pressure gradient versus (flow rate, diameter and bulk velocity). The results of the numerical model are compared with the results obtained experimentally for a permeameter constructed for this purpose. The numerical model proposed is used to vary the geometry of the permeameter and determine the best conditions of operation.
